Marshall & Gordon

HUMAN RESOURCE MANAGEMENT Assignment 2 Marshall & Gordon: Designing an Effective Compensation System Situational Analysis Paul Nasr is the president of Morgan Stanley (MG) who has nearly 20 years of experience in the capital markets business. He assumed the leadership of the newly created Capital Markets Services division. The Capital Markets division is an interdisciplinary entity created to serve as a link between the Investment Banking division and the sales and trading arms of the firm, Equity and Fixed Income.The division is created to provide the clients with more focused attention and service. The employees in this division were also expected to generate business from organizations that were not previously clients of Morgan Stanley. Nasr hired Parson who is a successful, young banker and has a proven track record in the financial sector. He believed Parson is the right person in growing the capital market services arm of the firm. Parson had ten years of experience and possess es strong relationships in the banking and insurance industries.He didn’t have the Ivy League background that other employees in Morgan Stanley had had but he has the required experience working in bank and investment houses. He quickly rose up the ranks to become the Managing Director of a small firm. He is assigned the title of Principal and is expected to give analytical solutions to complex problems, have good client relations, understand the clients’ objectives and constraints and identify and create business opportunities for MG. He should possess excellent negotiation skills and also be a team supervisor and leader of the Investment Banking Department. 60O FEEDBACK PROCESS This process is a feedback solicited from superiors, peers, subordinates and internal clients as well as self-evaluation of an employee to gauge his/her performance. The inputs from this feedback helps in understanding and quantifying an employee’s strength, his/her deficiencies as well as gives cues for required developmental trainings and appraisal/promotion. This process minimizes the perceptional evaluation from a single source and gives a sense of ownership and fair judgment to one’s self perception.During the performance evaluation before his supposed promotion to the managing director or partner of the firm, Parson is credited for his good marketing skills, knowledge of the market and product, aggressiveness in making the deals with clients, his ability to cross-sell products to the clients. But he also got some very negative comments for being judgmental, not being a team player, not being professional at times. Nasr, though, defended that Parson is still young in MG and needed time to align himself with the firm’s values. Problem DefinitionNasr is staring down the barrel on whether to promote Parson as a Managing Director/Partner of the firm or give him more time. He also did not want to lose Parson who might leave the firm if he did not get the promotion. Options Nasr has three ways of coming out of this quagmire: a. Promote Parson and assume that he will get better with time. b. Hold his promotion till the next evaluation and give him a chance to overcome his shortcomings. c. Terminate his employment because his work doesn’t align with the firm’s core values. Evaluation Criteria:The following criteria should be used to evaluate the options available to make a fair decision: a. The employee should be result-oriented b. He should have good interpersonal skills c. He should bring new business to the firm d. He should be able to win the confidence of the clients e. He should possess both the market and product knowledge f. Understand the needs of the clients and utilize his market knowledge to work with the product specialists in providing a new product g. He should be a good team player h. He must possess good analytical skills to solve complex issues. Evaluation of Options a. ) Promote ParsonRob Parson is an excellent employee who has turned around the Capital Markets Services division in Morgan Stanley in an unconventional way and brought in new business through his aggressive marketing skills. He is instrumental in improving the market share from 10th position to 3rd position, during which the market share rose from 2% to a substantial 12. 2%. Since the division is new, he had to adopt these methods to win the clients’ trust. He introduced clients to his colleagues and also is able to cross-sell products. He might not always be social given his responsibilities but he is not antagonistic towards anyone.Moreover, Parson acknowledges that he is poor at self-promotion and is not in sync with the organization’s goals. b. ) Hold his promotion Nasr is in a position of responsibility and authority. If he chose to promote Robert Parson just on the basis of results, it would create a wrong precedent to other employees that they can bypass the Morgan Stanley culture and still get promoted. In addition, Rob Parson is personally recruited by Nasr and, giving a promotion to Parson despite the interpersonal issues indicates adaption of unfair practices in the performance evaluation.Also, the newly implemented 360-degree feedback stresses on culture of the firm rather than goal orientation. In this case, Parson is more goal-oriented than organization-oriented. So, his promotion being put on hold could be a viable option at this juncture. c. ) Terminate his employment Parson came from a background where he ought to be more result-oriented than being a cultural-fit in pursuing his goals. By adapting this strategy, he had created an internal notion that employees can bypass the core values of an organization to achieve one’s goals.This could undermine the very working culture of the firm and would lead to internal conflicts within the employees. So, his employment could be terminated to maintain the stability within the organization. Recommendation It can be concluded that he is a valuable asset to the firm given his contributions and should be promoted to the Managing Director position. He could undergo trainings on team building and interpersonal skills to further improve himself. The 360-degree performance evaluation can be used to give feedback to Parson on both his strengths and areas where improvement is needed.

Sport in Lithuania Essay Example | Topics and Well Written Essays - 2250 words

Sport in Lithuania - Essay Example (Klimas, V. & Baublyte, M. 1997) The country's economy is based on a free market that has capitalistic principles. The government of Lithuania pursues a flat rate tax and the rate of unemployment in this country is very low and this has further led into the notion of the Baltic tiger. However the country has been in transition fro an economy that is communistically planned but it has also faced crisis in its financial sector partly because of the financial crisis in Russia. The country's GDP has grown by a rate of 7.5% since the year 2005 whereas the rate of inflation grew by 3%. The country's purchasing power parity is approximately $48.49 billion and the per capita income is estimated to be $15, 858. On the other hand the industrial composition of this country is estimated to be 33% the countries industries are inclusive of machine tools and metal cutting, television sets, food processing computers, optical equipment amongst others. The earliest inhabitants in Lithuania date back to 10,000 BC. The Lithuanians are neither Germanic nor Slavic even though the country's union with Germanic, Poland and Russian colonization as well as settlement left the religious and cultural influences. (K. Dawisha, B. Parrott 997) In the country of Lithuania the homogeneous population is the Lithuania and according to census that was conducted in the year 2001 84% of the population positively identified themselves as Lithuanians, 7% as the poles, 6% as the Russians, and 1.5% as the Belarusian's and 2% as the members of the other ethnic groups. The high percentage of the Lithuanians in the country could be highly influenced by the fact that in the 1990s the Lithuanian government embarked on granting citizenship to any person who lived in the country and also wished to have the country's citizenship. (Kaunas medical academy 1998) In the country's Vilnius region there is a higher concentration of the Poles. On the other hand the Russians in the country even though they are not very numerous such as the poles they are more evenly scattered even though they lack strong political parties. The ethnic composition in Lithuania has however undergone very dramatic changes with the most prominent changes being the extermination of the Jewish population during the holocaust. It is easier to obtain citizenship in this country than in the many other European countries. All the citizens in this country have had the liberty to freely participate in any sporting activity that exists in the country. However some of the sporting events have either marginalized the males or the females. For instance the country's football teams consist of only male parties whereas the majority participants in the cycling sport are the females. Religion. Majority of the Lithuanians belong to the Roman Catholic Church which has been the

Management of Acute Post Operative Pain in a Clinical setting, by third year nursing students - Assignment Example These reflections and observations are later assimilated and put into abstract concepts thus producing new implications for action which can be actively tested and in turn creating new experiences. In a clinical setting, instructors or teachers are expected to apply the four stage learning cycle which is a theory by Kolb. The four categories as stipulated by Kolb are concept experimentation (CE), reflective observation (RO), abstract conceptualization (AC) and lastly active experimentation (AE). Since the learning session is in sort of a discussion in a classroom, the teacher will be required to theoretically elaborate on the four stages or processes towards achieving knowledge (Kolb 2001). For instance the teacher would display an image showing how a doctor attends to a patient and the various processes that are carried out during the treatment procedure. If the learning session was practical, the students would be required to reflectively and keenly observe what the doctor is doing . This would in turn make them absorb any useful information from the experience and thus they would be in apposition to conceptualize the treatment procedure that they witnessed. ... Immediate of concrete experiences lead to observations as well as reflections. The following mentioned reflections are then internalized and translated into abstract concepts just like it has been elaborated thereon earlier, with implications for appropriate exercise which the student can actively experiment with. This further creates space for new experiences. Teaching with patients Teaching in a clinical setting or rather environment has the advantage of using real patients. This offers students some challenges but it requires close supervision so as toe ensure that the patients are in good condition. Students can in turn learn more from some patients than others. Patients chosen for teaching should be friendly, available and willing to talk and be in a position to accept examinations by students at the appropriate or stipulated time. They often feel that teaching students is a way of making some sort of sense of their illness or giving more information concerning their condition ( Petrie et al. 2009). Patients who may be willing to help the students learning process may have important information concerning their experiences of illness or have good, stable clinical signs. There should be no communication barriers unless the teacher is shedding light on how students should deal with communication difficulties from patients. Teaching with a patient may not only help students but may help their medical care; for instance if one wants a full history to be taken and recorded in the notes or consider an aspect of care which has not been explored before (Jarvis 1987). Patients are usually happy to take part in teaching sessions but it is

Managing Organizational Change - Case Study Example The residents of Honk Kong strongly believe that the way to drink water is to use the bottled variety, as they believe the health benefits and convenience is preferred compared to boiling existing tap water. The debate surrounds the problems associated with these views, however. Hence the purpose we must now address is to radically change the way people in Honk Kong regard their water supply. The current thinking is problematic on a number of fronts. However, it can be seen from history that there was a time when everyone in Hong Kong drank water from the tap. So what has changed Bottled water is now the preferred choice, despite the fact that tap water is for all intents and purposes, free. Hong Kong residents try to justify this by assuming the following: There is a counter-argument to this, but it seems to fall on deaf ears. In the end convenience seems to be a major factor, as with all consumer products. Here are some of the counter arguments: (South China Morning Post, 2007) In addition to the above plus point and minus points, other factors need to be considered by the consumer. For instance buyers need to be aware that tax is being charged on the cost of a bottle of water. The long term solution of course is to improve the general water supply quality. Re-education needs to take place as too many people feel that bottled water is the only option. In the end a restriction policy may have to be put in place to make the production cost higher. Eventually this will make it more difficult for the end consumer to purchaser. The only problem with this approach is that it is not guaranteed to have the desired effect. Chapter 2 The Change Process So, how do we change the habits of approximately "6.92 million" (Bureau of East Asian and Pacific Affairs, 2008), Hong Kong residents Well, if we follow Kurt Lewin's model there are a few things we can do. We will take this one aspect at a time, and see where we can fit in an appropriate solution or scenario fitted for the stage in question. Unfreeze. The objective here is to establish a good relationship with the people involved, and enable others to realize that the present behaviours are not effective. As with all change of a radical or not-so-radical nature, we would need to minimize the resistance to change. Easier said than done perhaps In some films and books you often read about masses of people who have had their perception of a situation changed just because of a single appealing speech.

Distribution Systems - Essay Example They are carried to different areas to be distributed in different retail outlets. At times, the distribution centers are located near the bottling plants of Coca Cola. The objective of the distribution centre being near to the plant is easy transportation of the bottles into the carrying vans (Berry, â€Å"ColaLife MDCs and Coca Colas Manual Distribution System†).

Finally the paper suggests how a Microsoft R&D initiative in the form of an FDI may turn to be successful international marketing effort in Russia. Microsoft -A corporate profile and Organizational culture "Microsoft is the global leader in software, services and solutions. It was founded in 1975 by William H. Gates III, better known as Bill Gates. In the fiscal year ending 30 June 2006, Microsoft employed 71,553 people and had net revenues of $44.28 billion. Microsoft operates from 9.9 million sq. ft. of office space all over the world. With headquarters in Redmond, WA, USA, it has subsidiaries in 104 countries and operation centers in Dublin, Ireland; Humacao, Puerto Rico, USA; Reno, Nevada, USA and Singapore". (Profile, 2006)Microsoft's history is full of important milestones. Some of the important dates in Microsoft's history can be listed as follows: on 25 June 1981 Microsoft was incorporated ; on 12 August 1981, IBM introduced its personal computer with Microsoft's 16-bit operating system, MS-DOS 1.0 ; on 13 March 1986: Microsoft's stock went public ;on 22 May 1990 Microsoft launched Windows 3.0; on 25 June 1998 Microsoft launched Windows 98;on 22 June 2000: Bill Gates and Steve Ballmer outline Microsoft's .NET strategy for Web services ; on 31 May 31, 2001: Microsoft launched Office XP ;...

Finally the paper suggests how a Microsoft R&D initiative in the form of an FDI may turn to be successful international marketing effort in Russia. This essay makes a conclusion that Microsoft would do well to remember that Russians possess excellent technical education, understanding of networks and, programming knowledge. It would be an ideal human resource strategy to recruit out of such a talented pool which even had tenacity to hack US software in 1980 so as to make Russian programmes work. As of today Russia has many skilled people but only a few jobs for them. Such unemployed talent is involved in social evils like hacking for earning money and name. Moreover hacking operates in gangs, groups and clubs which are well organized and have basis in social communal system of organization. Such groups have often been persecuted for global level hacking. Microsoft should ideally convert its policy of community work for Russian reality to wean away such talent. Russians have strong desire for Internet access, but find it to be an expensive affair.

Strategic Management Discussion Paper - Essay Example supposed to save time since tasks would not have to be passed from one team to another if a cross functional team is used to handle the entire production cycle. The idea is also helped by the emergence of business information systems which allow the sharing of information between departments making cross functional teams more powerful than departmental teams alone. There are some situations where reengineering is not only a good point on the agenda, it becomes a necessity for survival. The emerging e-business environment and the world of online sales means that not only the business models followed by companies but also the methods of doing business have to be changed (Rayport and Jaworski, 2000). The case of Apple is a prime example where the business process as well as the way sales were made by the company were changed and reengineered due to the availability of technology and the presence of a new business process (Smith, 2006). Of course there can be situations where a reengineering of a process may not be viable such as the operations of a hospital where health of the patient may be more important than simple profits or an airport where safety is often more important than efficiency. A high level of turnover at a company can be sign of many different things but given the other situations which are present at the company, it seems that there are quite a few problems at Milinder Recycling which are leading to the present situation of high turnover amongst new employees. While it is heartening to know that most of the older employees have been retained, the lack of new hires sticking it out shows that there is a significant problem with the recruitment and retention process for junior members (Welch, 2005). The company needs to establish an orientation program as well as provide some on the job training for new recruits who can be shown why Milinder is a good company to work for. Since the company has noticed that older employees are easier to retain they can

Domain Names as Internet Properties Essay Example for Free

Domain Names as Internet Properties Essay What are your long term plans for your domain name? Do you expect to convey the name and the goodwill associated with it to an interested buyer or bequeath it your heirs? Perhaps you intend to use the domain name to secure a loan for a business expansion or for your childs college tuition. You may be in for a surprise. The intellectual property community asserts that domain names, as source indicators, are akin to trademarks. However, trademark law cannot be effectively grafted on to domain names because of the discrepancies over geographical boundaries and context-sensitive use. In order for a trademark registration to issue, the mark must be used in interstate commerce to identify the source of a class of goods or services. Identical trademarks can co-exist so long as they are associated with non-competing types of goods or services or are used in different geographic areas. Domain names are registered on a first-come, first-served basis. The first individual or company to complete the registration template for an available name gets the sole right to be associated with it. For a reasonable fee, currently hovering at $10 a year, the registrant can brand and propagate the name in a worldwide marketplace. The registrant receives the exclusive right to use that name for a website presence, global e-mail, and network file transfers. But every domain name must be unique, and it is this technical requirement that makes domain names potentially valuable resources which are substantively different from trademarks. Compaq Computer Corp paid $3. 35 million in July 1998 for rights to ALTAVISTA. COM, purchased from a California start-up called Alta Vista Technology. The transaction included existing traffic of a half million visitors a day who were already expecting to find the Alta Vista search engine at that domain name. As the price bar for domain names rises, NSIs customers may resist being subject to the vagaries of the registrars feudal regime. Simple and unencumbered ownership endows the registrant with a type of predictable, if limited, sovereignty. Through legislation and judicial acknowledgment, registrants who meet certain individual responsibilities should be allowed a perpetually renewable and assignable right to enjoy this new source of wealth. Many domain names have become the cornerstone of multimillion-dollar business plans. In the fall of 1999, VirtualVineyard of Palo Alto, California, acquired Wine. Com of Napa, primarily for its domain name. While the $3. 3M-plus acquisition included an operating business, the CEO of Wine. Com estimated that about 70 percent of his companys value was its name. The current controversies over domain names highlight the interplay of technology, law, economics and politics. Court opinions trail societys changes and conundrums resulting from technology of recent vintage. Yet, nearly everyone agrees on one point: domain names are caught in a legal thicket. If domain names are property, then existing contracts such as NSIs harsh Service Agreement must be rewritten. Although the implications of the Umbro decision are yet to be fully assessed, and NSIs appeal remains to be heard, the magistrate recognized that each knotty domain name dispute before the court may be breaking new legal ground.

Clinical Practice Analysis Nursing Models Health And Social Care Essay

Clinical Practice Analysis Nursing Models Health And Social Care Essay Concepts should not be considered as either being permanent or static but should be considered open to new knowledge, perception, experiences and also data (Alligood and Tomey 2006). The nursing models were established to help clinical nurses in developing new roles and partnerships and also create better models of nursing care in order to facilitate a better clinical practice (www.health.nsw.gov.au/nursing/projects/models_of_care.asp). Nursing models are usually referred to as operational models for redesigning the nursing practice that will provide better nursing care for the patient on an organizational setting, primarily hospitals and long term care facilities. The models however can take a different form on the organizational level. They however only mean that that there has been some form of redesigning. This redesigning is usually mainly at the patient care delivery level or the nursing level. The only way to differentiate such models at the level of organization is by attaini ng those that do not care delivery. These are mainly levels such as innovative pay and also the programs of clinical advancement. Nursing practice models differ from the traditional models in either of the following structural dimensions. It is either through the degree to which the practice by individual nursing is differentiated based on their individual educational level, the degree to which nursing practice is more of self managed rather than managed by traditional supervisors, the degree to which case management is deployed and also the degree by which teams are employed. Teams in this case mean either nursing or multi-displinary. According to Mayer, Madden, and Lawrenz (1990), the models that they evaluated have varying degrees of employing various structural approaches to reorganize the nursing practice. Past studies and also the present studies show reflections on the applicability of the models and also the nursing models. This allows the validation and construction of new action forms in nursing care. It also helps to identify limits and relations between professions and individuals who are in need of care. In order to give a description, explanation, forecasting or even a prescription of nursing care, there is need to have articulated and communicative conceptualizations of reality which can either be invented or discovered. Case study: HIV/AIDS patients Among many cases that affect the human nature other than the cancer kind of diseases, Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS) has the greatest negative effect on mankind. The case study within the practice which best utilizes the nursing models is on the Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS). This case study best shows how the nursing model by Dorothea Orem can best service the patients and bring a form of relief to the patients. There have been models and theories that have been put in practice or give an explanation of the self-care related phenomena guide solutions that respond to the involved people ¿Ã‚ ½s needs and interests and equip nurses to help patients take care of themselves, as AIDS is a chronic illness that depends on the patient ¿Ã‚ ½s personal care to gain a better quality of life and prolong survival. Models including that of Dorothea Orem are used in nursing to ensure that there is adequ ate care given to those with HIV/AIDS. The use of this model or theory is because those who suffer HIV/AIDS have low immunodeficiency. This has a great effect on the normal functioning of the body. It however rests upon the patients to ensure that they maintain good health. People suffering from HIV/AIDS require constant care and support from the society. They also require not to be looked down upon by those who offer the care delivery to them. It therefore shows that the model of nursing by Orem can easily boost the morale of the patients if they a re given a chance to have the self care by themselves. It however also requires that there be moderate to high levels of participation by the health care deliverers in order to ensure that the patients are well equipped on how to go round the self care. Nursing models by Orem Models are considered conceptual reference frameworks, constructed representations on some aspect in the environment, using abstractions as fundamental blocks. The self care model of nursing or better known as the Orem model of nursing was established by Dorothea Orem in 1959. In her theory of administering care the patient is looked upon or is encouraged to be an independent person. This helps in the recovery of the patient as they are directed to use the best ways possible to ensure their well being. Self care is considered as an individual ¿Ã‚ ½s performance towards a better health, life and also well being through practice of given activities. The recovery and development of health is achieved when a patient apprehends the orientations. This helps to retain the structural integrity and also the human functioning. For those suffering Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS), there are diseases which are related that occur. They may include the acquisition of opportunistic infections as the body has a low immune system, difficulty in taking sufficient food intake, lack or deprived sleep, nausea and/ or altered palate due to collateral medical effects, weight loss, fatigue, an decrease in body mass. Other than the physical changes, the patient may also have an onset of psychological alteration such as low self image and self esteem. There are also changes in lifestyles of the patient due to maybe prejudice, side effects of the medication and even constant and frequent visits to the health centre. Areas of changes The self care model by Orem consists of mainly three theories which revolve mainly around the nursing theory, self-care deficit and also the self care theory itself. On the theory of self care there are three levels that are of concern such as universal care, health deviation and also developmental. This means care which aims at maintaining the integrity of human functioning and structure. According to the self care deficit theory, it shows that the patient has to be dependent and in a situation whereby the patient is incapable or has limitations to providing self care. This is what needs to be changed in the Dorothea Orem ¿Ã‚ ½s model of nursing in order to deliver better care. By doing away with such theories it will prove better and well managed to finally offer better care towards the patients. It therefore becomes relevant to view such a case scenario as a way to improve self care through the use of the Orem nursing model where a patient should be considered as an independent person. There have been researches done that have articulate the use of this model of nursing. Outcome of the use of the nursing model by Orem a. The use of the theory by Orem by patients suffering from HIV/AIDS As such was the case scenario of patients in an educative proposal of how to have eye self exam by those who suffer from Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS). There were several detailed diagnosis that were identified from most of the patients. Based on the profile that was as a result from the analysis of the patients, it proved that patients require help. The demand on self care on universal and developmental level ensures that patients get moderate if not high levels of help. Basing the facts from the deduced results it showed that there was a level of competency in the patients. This shows that the patients can conduct their own eye self exam. The results also justify that for patients suffering HIV/AIDS, it is possible for them to have adequate nursing care. Through the analytical questions that were posed in order to achieve the analysis of the model showed that nursing care systemization for self-care among HIV/AIDS patients, using the n ursing process; to the patient ¿Ã‚ ½s possible accomplishment of the eye self-exam; to the identification of HIV patients ¿Ã‚ ½ self-care attitudes and deficits through the universal, developmental and health deviation requisites. Besides, the nursing model collaborated as a method to help patients. The resulting results show that the Orem ¿Ã‚ ½s theory can give guidance. This guidance however serves as a guide to how care delivery is done on those with HIV/AIDS. It also elaborates more on the need to have assessment on the HIV/AIDS patient on self eye exam. The analysis of the study also showed that the nursing model by Dorothea Orem can also be used in the nursing curriculum. b. The use of Orem ¿Ã‚ ½s model of nursing involving the HIV/AIDS patients The analyzed study offered important information to guide nursing research, as it demonstrated that the use of Orem ¿Ã‚ ½s Theory permitted testing an eye self-exam teaching model in HIV/AIDS patients, which can be included in the nursing curriculum. There were discoveries that were made in the Orem ¿Ã‚ ½s theory. This included the fact that there was little or small input from the limited number of participants. It therefore proved hard to make a possible. However, there was qualitative results that made it possible to have a view on the competency in HIV/AIDS patient to run an eye self test. The tested propositions were based by the fact that a higher proportion of HIV patients at different stages had irreversible eye alterations due to lack of early diagnosis and treatment. It therefore goes to show that patients require help for universal development and health deviation requisites. c. Orem model of nursing for the purpose of nursing management Based on the research done on people with HIV/AIDS, there is a considerable gap that the nurses should bridge. Mainly this gap is mostly in the learning of nursing based on the educative and supportive system of nursing there has been detailed nursing curriculums that help in implementing the Orem ¿Ã‚ ½s model of nursing. The outstanding results from the use of Orem ¿Ã‚ ½s model in nursing showed that there could be use of the model in the management of the nursing in care services. This was a measured achievement towards self care for patients suffering from HIV/AIDS. It proved to be a success and therefore can be used in the nursing management. The practice of nursing is becoming more targeted as the self care proved to be an instant success. Mainly after the nursing interventions, the care quality in nursing can be measured to form an assessment. d. Better instruments for future and further diagnosis of diseases Based on the findings of how effective the Orem ¿Ã‚ ½s model of nursing is on Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS) it only goes to show that with future studies of other diseases, this Orem ¿Ã‚ ½s model of nursing can be utilized to the advantage of the patients and also to the advantage of the nursing practice as a whole. In the practice of this Orem ¿Ã‚ ½s model of nursing, it proves comforting to the patient which should be the general idea behind nursing (Alligood and Tomey 2006). It offers comfort to the patient as they have the knowledge that someone else has faith in them to take good care of themselves. It also boosts their morale in knowing that they are yet capable of taking care of themselves to attain better health General conclusion For nurses who undertake the use of Orem ¿Ã‚ ½s model of nursing they can easily find out gaps or self care deficits which they can try to fill in. The act of learning more in order to fill in the deficit can also help in the diagnosis which might be corresponding. By the use of the Orem ¿Ã‚ ½s model of nursing, it becomes easy for those in the nursing practice to identify means and ways through which they might better the practice. Basing on facts that the Orem ¿Ã‚ ½s model of nursing was established in the early 1965, it has been used widely in nursing areas such as on pregnant women, HIV/AIDS patients, adolescents and also hypersensitive patients. There has been progress from theory to practice by the use of the use of the model in nursing by Orem. There is proven and theoretical framework as it has helped nurses to offer support to patients of HIV/AIDS. Besides just intervention for those with HIV/AIDS, the model of nursing by Orem ensures that attitude of the patient and a lso the self care deficits are clearly identified. It therefore proves that the model in nursing by Orem can is actually a valid instrument. It can therefore be used to bridge the gap between the researchers and also the research subject. As a means of ensuring that those in the nursing practice utilize the Orem ¿Ã‚ ½s model in nursing, there can be a venture into other areas other than HIV/AIDS to areas such as diabetes. By the use of the Orem ¿Ã‚ ½s model in nursing it has opened up more opportunities through which support education can offer. There is better service offered since the Orem ¿Ã‚ ½s model in nursing was established and more research in this area is proving fruitful. This is because of the research done based on people with Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS) has been seen as a step closer to ensuring that the patients do not suffer. It also has ensured that there is better treatment both at a physical and psychological l evel. Though it might prove as a remedy or cure to the disease it has definitely given the patients a better understanding of themselves. It has also created ways in which the patients can be self reliant based on the stages of the Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS). Recommendations It therefore goes without saying that the Orem ¿Ã‚ ½s model in nursing is a true model that should be utilized more for the sake of the patients. It helps in boosting the self esteem of the patient which giving a detailed analysis to those in the profession of nursing. It provides a better view on how strategies should be laid out in order to achieve better health care delivery. Patients no matter the kind of ailment they suffer from but especially those suffering from Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS) should be taken as independent patients. They should be taught various ways of self care other than the eye self care. Through such ways it proves profitable for both the patients and also those in the nursing practice. The model in nursing by Orem proves a sufficient way to manage the practice of nursing and on the other hand creates a study for other patients who might benefit from the model.

Conceptual Model of Strategic Data Projects

Conceptual Model of Strategic Data Projects CHOSEN SCENARIO: VINCES VINYL Analysis and Design A. Conceptual Model: A conceptual model, or a summary-level data model, is generally used on strategic data projects to describe an entire organization. As the most abstract form, it is useful in communicating ideas to a wide variety of stakeholders. Platform specific information, e.g., data types, is excluded. Other implementation details, e.g., procedures and interface definitions, are omitted. CDM (Conceptual Data Model) is typically created without consideration of database concepts and used in the initial planning phase. Business practice, rather than information similarities, defines relationships. In this phase, it is irrelevant how information is stored and managed, but primarily understanding how stored data is used is crucial. It provides the overall structure of the database and high-level information about the subject areas and/or data structures of an enterprise. Its simple purpose is to establish the Entities, their Attributes and their high-level relationships. In other words, there is little detail, consisting of the basic Entities along with their simple relationships. If any Attributes are included, they are loosely typed (e.g., no length settings). Connectors between Entities do not define relationships to specific Attributes. (UC Davis). Common characteristics of a CDM (DataModel.com): Enterprise-wide coverage of the business concepts. (For example, Customer, Product, Store, Location, Asset.) Designed and developed primarily for a business audience. Contains around 20-50 entities (or concepts) with no or extremely limited number of attributes described (sometimes minimized for printing on one page). Contains relationships between entities, but may or may not include cardinality and nullability. Entities will have definitions. Designed and developed to be independent of DBMS, data storage locations or technologies. In fact, it would address digital and non-digital concepts. This means it would model paper records and artifacts as well as database artifacts. Conceptual Model for Vinces Vinyl: The primary entities are: the owner, vendors/suppliers, customers/buyers, employees and albums. The owner purchases albums from vendors/suppliers, sells them to customers/buyers and employs part-time help, who stocks and also sells the albums to customers/buyers. (See screenshot below.) Logical Model: A logical data model, or a fully-attributed data model that is independent of DBMS, technology, data storage or organizational constraints, typically describes data requirements from the business aspect. Also referred to as LDM, it represents the (entire or partial) business requirements of an enterprise and is developed before the physical data model. It involves using the business information discovered during CDM and translating it into a relational style, empirical layout of the data. While the data modeling uses a relational model notation, the resulting data implementations using relational technologies are not required. This technique includes more detail, or Attributes. Nevertheless, it is still generic since it is not bound to a specific DBMS. It helps to define the detailed structure of the data elements in a system and the relationships between data elements. The model refines the data elements introduced by a Conceptual data model, just as it forms the basis of the physical data model. The process of creating a logical model (based on a conceptual model) involves (DataModel.com): Setting the Attributes. These later become Table Columns. Setting the Relationships. At this level, Primary Keys, Foreign Keys, etc. are not yet set. This level can be used to verify and adjust the Connector multiplicity (or, cardinality) details that were established for relationships in the Conceptual model. Common characteristics of a logical data model (DataModel.com): Typically describes data requirements for a single project or major subject area. May be integrated with other logical data models via a repository of shared entities Typically contains 100-1000 entities, although these numbers are highly variable depending on the scope of the data model. Contains relationships between entities that address cardinality and nullability (optionality) of the relationships. Designed and developed to be independent of DBMS, data storage locations or technologies. In fact, it may address digital and non-digital concepts. Data attributes will typically have datatypes with precisions and lengths assigned. Data attributes will have nullability (optionality) assigned. Entities and attributes will have definitions. All kinds of other meta data may be included (retention rules, privacy indicators, volumetrics, data lineage, etc.). In fact, the diagram of a logical data model may show only a tiny percentage of the meta data contained within the model. A logical data model will normally be derived from and or linked back to objects in a conceptual data model. A physical data model is a fully-attributed data model that is dependent upon a specific version of a data persistence technology. The target implementation technology may be a relational DBMS, an XML document, a NoSQL data storage component, a spreadsheet or any other data implementation option. Logical Model for Vinces Vinyl: Necessary aspects of the DBMS are represented to address the business solution. (See screenshots below.) Physical Design: Physical level modeling involves adding platform specific detail to the model, i.e., detail specific to the DBMS, where the database is to be deployed. This can be accomplished by creating a copy of the logical model and by adding the physical definitions. It includes all required tables, columns, relationships, and database properties. It visually represents the structure of the data, as implemented by a relational database schema (e.g., tables, columns, indexes, constraints, primary and foreign keys). In other words, by defining a physical data model, the database schema can be derived automatically. The logical model, which was derived from the business concepts (or, conceptual model), is in turn adapted for database deployment. PDM, as it is sometimes known, involves the final stage of planning. This stage involves an absolute design of the database implementation, which is often completed by a data architect, or a database administrator. As such, the CDM, LDM and PDM phases are finalized. The key aspects of PDM are (DataModel.com): For each Class: The Stereotype must be set to Table. The Database setting must be set to a specific DBMS. Update the Attributes to reflect Columns Typed to the specific DBMS Field types. Add more detail to the Connectors (relationships), in order to define the Primary Key (and Foreign Key) linking. Further details can be added to the derived physical model. These include setting: Stored Procedures: (A stored procedure is a group of SQL statements that form a logical unit and perform a particular task. Stored procedures are used to encapsulate a set of operations or queries to execute on a database server. They can be compiled and executed with different parameters and results, and they can have any combination of input, output and input/output parameters.) Views: (A Database View defines a subset of the database, aggregated into a dynamic, virtual table. The information presented by a Database View is not physically replicated. It is simply automatically derived based on the query that defines the view.) Common characteristics of a physical data model (DataModel.com): Typically describes data requirements for a single project or application, sometimes even a portion of an application. May be integrated with other physical data models via a repository of shared entities Typically contains 10-1000 tables, although these numbers are highly variable depending on the scope of the data model. Contains relationships between tables that address cardinality and nullability (optionality) of the relationships. Designed and developed to be dependent on a specific version of a DBMS, data storage location or technology. Columns will contain precision- and length-assigned datatypes. Columns will have nullability (optionality) assigned. Tables and columns will have definitions. It will also include other physical objects such as views, primary key constraints, foreign key constraints, indexes, security roles, store procedures, XML extensions, file stores, etc. The diagram of a physical data model may show only a tiny percentage of the meta data contained within the model. Physical Model for Vinces Vinyl: This model builds on the nonphysical (conceptual and logical) models that have been crafted. (See screenshot below.) (Special note: In case the above sample is insufficient, I am including the database diagram that I also submitted for the Scenario Activity.)

How Shelley and Fowles Present the Socially Excluded Essay -- Frankens

How Shelley and Fowles Present the Socially Excluded Men are numbered among beasts who renounce society, whereby they are destitute of laws and the ordination of civility. Hence this ensures that men, in creation are best, but when averse to justice and the law, are the worst of all creatures. (p.36 intro The Tempest by William Shakespeare, edited by Frank Kermode 1961) For the purpose of this essay, I shall focus my comparison on Victor and Clegg and analyse the language they use. I will also explore the form and structure used and give a personal response which will include some commentary about the novels in terms of their social/historical and literary contexts. People's behaviour in social roles makes possible the life of a society and its members. Social roles are learned from culture, which defines how they should be performed. They are not instinctive. However, people learn many roles during childhood by observing their parents and other adults. But on the other hand problems may result if the demands of one role interfere with those of another. This situation is called role conflict. Victor and Clegg are excluded by society primarily because they have transgressed society's boundaries, that is to say, Victor plays God and creates "a new species which would bless him as its creator" p.52 ; his male monster is built from old body parts and strange chemicals because he is determined to learn about "the secrets of heaven and hell"p.37. Ironically, Victor creates a "hideous wretch" p.73 which is "an outcast in the world forever" p.129. However, this "filthy daemon" p.73 is initially gentle and has a kind, baby-like nature, just like normal humans. Paradoxically, the monster is actually ... ...is a creation abandoned and shunned by society and Victor his creator. Therefore Shelley's use of letters enables the narrative to shift from one character to another while remaining within the conventions of the standard novel. Letters are also used to good effect as a means of social interaction because characters are frequently out of immediate contact with one another. Walton never encounters his sister in the novel; his relationship with her is based wholly on the use of letters. The same goes for Victor as he often isolates himself from his loved ones but he does receive letters from Alphonse and Elizabeth and this marks attempts to connect with him. Again, the monster uses written communication in order to develop a relationship with Victor when, at the end of the novel, he leads him northward by means of notes on the trees and rocks he passes.

An Analysis of Wright’s Poem Saint Judas Essay -- Saint Judas

An Analysis of Wright’s Poem Saint Judas      Ã‚  Ã‚   Upon reading the poem "Saint Judas" by James Wright, the reader quickly realizes that the poem deals with Judas Iscariot, one of Jesus' twelve apostles.   The author describes Judas as "going out to kill himself,"(line 1) when he sees a man being beaten by "a pack of hoodlums"(2).   Judas quickly runs to help the man, forgetting "how [his] day began"(4).   He leaves his rope behind and, ignoring the soldiers around him, runs to help.   Finally, he remembers the circumstances that surround his suicidal intentions and realizes that he is "banished from heaven"(9) and "without hope"(13)   He runs to the man anyway and holds him "for nothing in [his] arms"(14)      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In order to understand James Wright's intentions in writing this poem, one must first have an understanding of the biblical story that it deals with.   According to the Bible, "Satan entered Judas, who was numbered among the twelve [apostles].   So he went his way and conferred with the chief priests and captains, how he might betray [Jesus] to them.   And they were glad, and agreed to give him money.   Then he promised and sought opportunity to betray Him to them"(Luke 22. 3-6).   The Bible goes on to document Jesus and the apostles during the Last Supper, and Jesus revealing his knowledge of Judas' plan to betray him.   He tells his apostles:   "But behold, the hand of my betrayer is with me on the table"(Luke 22. 21).   Judas later leads the officials to Jesus and identifies him to them by kissing Jesus.   "Now His betrayer had given them a sign, saying, 'Whomever I kiss, He is the One, seize Him...Then immediately he went up to Jesus and said, 'Greetings, Rabbi! and kissed Him"(Matt. 26. 48-49).   After Jesus is ta... ...ough Wright does not say it directly, this may even suggest that the victim Judas encounters could be Jesus on his way to be crucified.   Judas temporarily forgets his intent to kill himself and runs to the victim, ignoring the soldiers.   Then he remembers the Last Supper and the meal he ate with Jesus and the other apostles ("Bread my flesh had eaten"(12)), and his betrayal of Jesus with a kiss ("the kiss that ate my flesh"(13)).   He goes to the man and "[holds him] for nothing is his arms"(14).   In this line Wright compares Judas' payment for betraying Jesus to the fact that he now offers comfort for nothing.    Works Cited 1.

Britain And America Revolution :: essays research papers

Since the historical conflict between Great Britain and her North American colonies began to unfold, historians have searched for the reasoning behind it. Many experts have discussed the various reasons for the conflict. Some experts believe the conflict occurred because America and Britain had become vastly different social and political entities. Others say that economical disagreements caused the conflict. However, these economical and social forces worked hand-in-hand to slowly erode away the binds that held America to its Mother Country. The traditional liberties of Britain and the newly established liberties of America were very different. After the French and Indian War, the colonies were “heavily'; taxed to sow together the damaged British pocketbook. These economical problems and social distinctions needed to be mended simultaneously or the war could not be avoided.   Ã‚  Ã‚  Ã‚  Ã‚  First, the traditional liberties of Britain were considerably different from the political and social origins of America. From the beginning, America developed different character than its Mother Country of Great Britain. In New England, where the seeds of revolution were sown, merchants used their shipping trade to defy English duties on sugar. As a result of this, additional troops were sent to the colonies to enforce British laws. Later, when the Quartering Act was passed, Americans complained against not only the taxation, but also an infringement on their rights of property. Before the conflict between Britain and France over the Ohio Valley and Canada, America was given practically free reign over its political liberties too. It set up colonial legislatures and citizenship by the act of owning land. Its government system wasn’t based on birthright and a monarch, they were for individual freedoms and the right to participate in government. But when the “tyrannical'; King George jumped in demanding control of the colonies, they were angered and looked for a way to keep their liberties.   Ã‚  Ã‚  Ã‚  Ã‚  Second, America was taxed by the British government to decrease its national debt. Due to their differences in economic base, Britain was self-sufficient in manufacturing goods and the colonies in agriculture. They both needed each other to survive initially. Later, however, America grew more self-sufficient and was able to survive without Britain’s helping hand. America had developed ships to trade with, which were primarily based in the New England colonies. America developed a strong agricultural base and crop source in the southern plantations and middle, “bread';, colonies. They also utilized these economic resources by generating trade with other countries such as France and her West Indian colonies.

Is There a Purpose of Life? Essay

Introduction Between ages, humans have metamorphosed to a different level with plethora of inventions and individual realizations, yet a universally acceptable answer to a prime question like ‘whether there is a purpose of life’ still remains as elusive as it had always been. Even the scientists too evade this question by saying â€Å"science can only answer ‘how’ rather than ‘why'† (Meaning, 2008). This state of affairs has divided three schools of thought – one, who says there is no purpose of life, two, who refutes the claims of the former and the third, who stays away from this debate. Thus this essay explores the views of the first and second schools of thought before coming to its own conclusion. There is No purpose of life. People who believe there is no purpose of life stress on objective evidence to build their premise. Since there is no concrete evidence of why life manifests in so many forms or procreates, it usually generates the inference that there is no purpose of life. There is no point in underestimating the collective intellect of the majority who find themselves clueless about what it could be the meaning and purpose of life mostly because they don’t find any. Even the in-depth analysis of life could only determine the processes, but not a valid reason behind it. After an exhaustive analysis of the question, NASA came to the conclusion that â€Å"life, all life, is the attribute of any system that is a) capable of replication, b) capable of every conversion in order to offset entropy and c) subject to the process of evolution†(Requadt, 2006) The prey-predator cycle ultimately turns to a level playing field where each living component shows its purpose as if either to utilize others or to be utilized by others. This cannot serve any clue as to why this game is going on, as the entire game is based on molecular activity at various levels, involving uncountable elements and processes under various time frames. Thus this enormity of the process itself defies any set principle to hint about any purpose behind all these. There is no tangible or universally acceptable proof that life stems from a single condensed form of power (as God or any superpower) that exists on and on even after the death of a living being. Thus the concepts like God creates living beings with a specific purpose or purposes are mere hypotheses backed by belief. Belief cannot be cited as evidence and therefore theories involving God as the creator of life also gets eliminated. The arguments placed by this school of thought clearly show that it does not allow any room to the individual human realizations regarding the purpose of life, as all humans do not certify such realization as commonplace experience substantiating the purpose of life on earth. This brings up one point to the fore – that the difference among humans in cognitive plane prevents them to achieve or align same kind of realization or understanding about life or its purpose and thus this school of thought indemnifies only the findings on the objective level. However, this seems too one-sided, because the significance of subjectivity in this issue is extremely important. There is Purpose of Life The other school of thought that admits about life having some purpose chooses to define it as something beyond ordinary comprehension and is â€Å"far greater than personal fulfillment† (Warren, 2004). This school relies on the model of superpower having its own purpose running behind creation and maintenance of the flow of life on earth. This school of thought recognizes individual experiences on cognitive plane and uses that to substantiate their claim while arguing about the limitation of humans or other living beings to capture the ‘big picture’ from objective angle. It is true that there is no dearth of instances that defies earthly logic, as for example, some accurate predictions done by individuals or someone claiming to receive some idea in dream or experiencing strange feelings that indicates the existence of a superpower. Discussion Since it is admitted that there are evidences regarding human inability to explain all the happenings on earth, it would be fair to say that if an issue (purpose of life) remains unresolved for so long, then it definitely hints at the inadequacy of knowledge that tries to define it. There is a distinct difference in analyzing a subject with limited range of knowledge (which is usually considered as rationality) and discovering or realizing something on cognitive plane. As for example, the purpose of life from the biological perspective is explicit; that it wants to maintain the identity of the form it takes (Luisi, 2008), though gradually metamorphosing to the tune of evolution. While this trait also takes place on the temporal plane of humans it cannot be explicit like its counterpart, as this development is intangible, where an individual reaches a new plane of realization on his/her own. While it is true that the individual account of any realization cannot be taken as a proof of the idea it presents, it cannot be ignored either. Then that would defy the process of development, which is evidenced by numerous human inventions that were initially considered as wild imagination of the individuals. However, individual account of any new experience on the cognitive plane is hard to inject into another individual to get the same result, mostly because of the difference in cognitive ability and consequently the great divide among individual perception on anything persists all along. Therefore, sporadic individual accounts of certain realization about the possible purpose of life, such as the accounts of some acknowledged great human beings who repeatedly told about a unique of discovery of our life’s connection with one supreme power, cannot settle the issue for once and all. As for example if someone says â€Å"the purpose of life is to recreate yourself anew in the highest version of the grandest vision you ever had about yourself† (Walsch, 1996), some will believe it, some will refute it and some will refrain from commenting on it. However, â€Å"not believing that there is a purpose of life will not prevent one from discovering it† (How to, 2008). Conclusion Primarily the question of whether there is any purpose of life commands the answer from the depth of perception about life. The above discussion clearly shows that the difference in cognitive abilities prevents humans to align their ideas about the purpose of life. While that seems disappointing, the increasing trend of overall temporal refinement among humans shows promise to settle this issue someday, as imagination and realization both command higher processing ability of   all possible inputs including he ones that even defy the reference frame of the living beings of the earth – that is, the reference frame of light. Over all it seems the discovery of the purpose of life depends on further manifestation of consciousness among humans or among the major part of them to establish it as a proven conclusion.

We The People

â€Å"We the People†¦ † Marked the opening of the country of America. These three words are the first three words written on the constitution which is known to be the framework of which this country is run. A country that gives all the promises of â€Å"liberty†, â€Å"justice†, â€Å"property†, and â€Å"life† through this document. This Is a document that has said they will give all in a secular manner. All matters that involve religion will not govern the country.If this said to be true, than certain practices such as Insuring Justice, does not come into agreement with their secular statement. This does not account for all forms of Insuring Justice but only for parts. The classification of crime Is divided Into two parts, the misdemeanors and the felony, Misdemeanors are punished with the use of temporary Isolation from society gall), mandatory aiding of the society (community services or reprimanding the Individual from the liberties of lif e.On the other side of crimes, a felony could also be punished using any of the methods mentioned afore, but In the case where one's life or liberty has been harmed. The methods are taken to a level of punishment higher than that of a misdemeanors; â€Å"death or imprisonment in excess of one year† (Defenestration. Com). Sentencing a person convicted of a felony to death is legal in some states and illegal in others.The death penalty is decided for those who commit crimes such as â€Å"First-degree murder with special circumstances; sabotage; train wrecking causing death; treason; perjury causing execution of an innocent person; fatal assault by a prisoner serving a life sentence† in some state or in the case of most states as long as en has committed capital murder with a certain number of aggravating circumstances. Some states have abolished the death penalty while others are in pending state where advocates of abolishing this form of punishment state that it is â₠¬Å"too costly and time consuming† (Death Penalty Information center).The removal of the death penalty is not an argument of whether or not it is moral or constitutional, but if is financially efficient. The death penalty is service of Justice in which the problem that has harmed not only those involved directly but the community as a hole is removed. The only goal that has been reached by this conclusion Is that the problem is no longer evident. Has Justice really been served to the one that has been deceased? Using the bases of the Constitution to run this country on the subject of legality, religion is not involved but the factual evidence of science would.Scientifically speaking, after the human passes away, the human body decomposes underground (â€Å"What Happens to Our Body After Death†) and this would leave the true victim and the defendant on the same level. Neither would suffer more than the other since both are no longer living, the only ones that would gain f rom the situation Is those who are alive. If the law of the land promises all what they were given from birth, this Is a form of justice that will not make the mark. The law should stick to that which it has promised not only benefiting those who are alive but those who left as well.Knowing what the one that has left is impossible but that person should not be made of equal to the one that has caused the misfortune. The correctness is punishment of the written. The Constitution is a secular document free of religious attribution since â€Å"the U. S. Government derives from people, as it clearly states in the preamble: â€Å"We the people of the United States, in order to form a more perfect Union†¦. â€Å"† (Walker, â€Å"The Government of the United States of America is not, in any sense founded on the Christian religion†).

Logical and Physical Data Models

The Physical Data Model (PDM) describes how the information represented in the Logical Data Model is actually implemented, how the information-exchange requirements are implemented, and how the data entities and their relationships are maintained. There should be a mapping from a given Logical Data Model to the Physical Data Model if both models are used. The form of the Physical Data Model can vary greatly, as shown in Figure 31. For some purposes, an additional entity-relationship style diagram will be sufficient.The Data Definition Language (DDL) may also be used. References to message format standards (which identify message types and options to be used) may suffice for message-oriented implementations. (Getting information from the LDM in form of file) Descriptions of file formats may be used when file passing is the mode used to exchange information. Interoperating systems may use a variety of techniques to exchange data, and thus have several distinct partitions in their Physi cal Data Model with each partition using a different form.The figure illustrates some options for expressing the Physical Data Model and an other table (in the original document) provides a listing of the types of information to be captured. A physical data model (or database design) is a representation of a data design which takes into account the facilities and constraints of a given database management system. In the lifecycle of a project it typically derives from a logical data model, though it may be reverse-engineered from a given database implementation.A complete physical data model will include all the database artifacts required to create relationships between tables or to achieve performance goals, such as indexes, constraint definitions, linking tables, partitioned tables or clusters. Analysts can usually use a physical data model to calculate storage estimates; it may include specific storage allocation details for a given database system. As of 2012 seven main databas es dominate the commercial marketplace: Informix, Oracle, Postgres, SQL Server, Sybase, DB2 and MySQL.Other RDBMS systems tend either to be legacy databases or used within academia such as universities or further education colleges. Physical data models for each implementation would differ significantly, not least due to underlying operating-system requirements that may sit underneath them. For example: SQL Server runs only on Microsoft Windows operating-systems, while Oracle and MySQL can run on Solaris, Linux and other UNIX-based operating-systems as well as on Windows.This means that the disk requirements, security requirements and many other aspects of a physical data model will be influenced by the RDBMS that a database administrator (or an organization) chooses to use. Overview Logical data models represent the abstract structure of a domain of information. They are often diagrammatic in nature and are most typically used in business processes that seek to capture things of im portance to an organization and how they relate to one another. Once validated and approved, the logical data model can become the basis of a physical data model and inform the design of a database.Logical data models should be based on the structures identified in a preceding conceptual data model, since this describes the semantics of the information context, which the logical model should also reflect. Even so, since the logical data model anticipates implementation on a specific computing system, the content of the logical data model is adjusted to achieve certain efficiencies. The term ‘Logical Data Model' is sometimes used as a synonym of ‘Domain Model' or as an alternative to the domain model.While the two concepts are closely related, and have overlapping goals, a domain model is more focused on capturing the concepts in the problem domain rather than the structure of the data associated with that domain. History The ANSI/SPARC three level architecture, which â⠂¬Å"shows that a data model can be an external model (or view), a conceptual model, or a physical model. This is not the only way to look at data models, but it is a useful way, particularly when comparing models†. [1] When ANSI first laid out the idea of a logical schema in 1975,[2] the choices were hierarchical and network.The relational model – where data is described in terms of tables and columns – had just been recognized as a data organization theory but no software existed to support that approach. Since that time, an object-oriented approach to data modelling – where data is described in terms of classes, attributes, and associations – has also been introduced. Logical data model topics Reasons for building a logical data model * Helps common understanding of business data elements and requirements * Provides foundation for designing a database Facilitates avoidance of data redundancy and thus prevent data & business transaction inconsisten cy * Facilitates data re-use and sharing * Decreases development and maintenance time and cost * Confirms a logical process model and helps impact analysis. Modeling benefits * Facilitates business process improvement * Focuses on requirements independent of technology * Facilitates data re-use and sharing * Increases return on investment * Centralizes metadata * Fosters seamless communication between applications * Focuses communication for data analysis and project team members * Establishes a consistent naming schemeLogical & Physical Data Model A logical data model is sometimes incorrectly called a physical data model, which is not what the ANSI people had in mind. The physical design of a database involves deep use of particular database management technology. For example, a table/column design could be implemented on a collection of computers, located in different parts of the world. That is the domain of the physical model. Logical and physical data models are very different in their objectives, goals and content. Key differences noted below. Logical Data Model| Physical Data Model|Includes entities (tables), attributes (columns/fields) and relationships (keys)| Includes tables, columns, keys, data types, validation rules, database triggers, stored procedures, domains, and access constraints| Uses business names for entities & attributes| Uses more defined and less generic specific names for tables and columns, such as abbreviated column names, limited by the database management system (DBMS) and any company defined standards| Is independent of technology (platform, DBMS)| Includes primary keys and indices for fast data access. Is normalized to fourth normal form(4NF)| May be de-normalized to meet performance requirements based on the nature of the database. If the nature of the database is Online Transaction Processing(OLTP) or Operational Data Store (ODS) it is usually not de-normalized. De-normalization is common in Datawarehouses. | A logical data m odel describes the data in as much detail as possible, without regard to how they will be physical implemented in the database. Features of a logical data model include: * Includes all entities and relationships among them. All attributes for each entity are specified. * The primary key for each entity is specified. * Foreign keys (keys identifying the relationship between different entities) are specified. * Normalization occurs at this level. The steps for designing the logical data model are as follows: 1. Specify primary keys for all entities. 2. Find the relationships between different entities. 3. Find all attributes for each entity. 4. Resolve many-to-many relationships. 5. Normalization. The figure below is an example of a logical data model.Logical Data Model Comparing the logical data model shown above with the conceptual data model diagram, we see the main differences between the two: * In a logical data model, primary keys are present, whereas in a conceptual data model, no primary key is present. * In a logical data model, all attributes are specified within an entity. No attributes are specified in a conceptual data model. * Relationships between entities are specified using primary keys and foreign keys in a logical data model.In a conceptual data model, the relationships are simply stated, not specified, so we simply know that two entities are related, but we do not specify what attributes are used for this relationship. Logical Model Design Physical Model Design Figure 5. A logical data model (Information Engineering notation). You also need to identify the cardinality and optionality of a relationship (the UML combines the concepts of optionality and cardinality into the single concept of multiplicity). Cardinality represents the concept of â€Å"how many† whereas optionality represents the concept of â€Å"whether you must have something. For example, it is not enough to know that customers place orders. How many orders can a custome r place? None, one, or several? Furthermore, relationships are two-way streets: not only do customers place orders, but orders are placed by customers. This leads to questions like: how many customers can be enrolled in any given order and is it possible to have an order with no customer involved? Figure 5 shows that customers place zero or more orders and that any given order is placed by one customer and one customer only.It also shows that a customer lives at one or more addresses and that any given address has zero or more customers living at it. Although the UML distinguishes between different types of relationships – associations, inheritance, aggregation, composition, and dependency – data modelers often aren’t as concerned with this issue as much as object modelers are. Subtyping, one application of inheritance, is often found in data models, an example of which is the is a relationship between Item and it’s two â€Å"sub entities† Service and Product.Aggregation and composition are much less common and typically must be implied from the data model, as you see with the part of role that Line Item takes with Order. UML dependencies are typically a software construct and therefore wouldn’t appear on a data model, unless of course it was a very highly detailed physical model that showed how views, triggers, or stored procedures depended on Logical Data Models (LDMs) represent data table (Entity Type) relationships. Logical Data Model Notations Entity Type Entity Type refers to a group of related data placed in an RDBMS (Relational Database Management Systems) table.An entity is an instance of an entity type represented as a single row in a data table. Relationships and Multiplicity Relationships illustrate how two entity types are related. Cardinality specifies how many instances of an entity relate to one instance of another entity. Physical data model represents how the model will be built in the database. A phy sical database model shows all table structures, including column name, column data type, column constraints, primary key, foreign key, and relationships between tables. Features of a physical data model include: * Specification all tables and columns. Foreign keys are used to identify relationships between tables. * Denormalization may occur based on user requirements. * Physical considerations may cause the physical data model to be quite different from the logical data model. * Physical data model will be different for different RDBMS. For example, data type for a column may be different between MySQL and SQL Server. Steps For Physical Data Model * Convert entities into tables. * Convert relationships into foreign keys. * Convert attributes into columns. * Modify the physical data model based on physical constraints / requirements. Physical v/s logical Entity names are now table names. * Attributes are now column names. * Data type for each column is specified. Data types can be different depending on the actual database being used. Data modeling is the act of exploring data-oriented structures. Like other modeling artifacts data models can be used for a variety of purposes, from high-level conceptual models to physical data models (PDMs). Physical data modeling is conceptually similar to design class modeling, the goal being to design the internal schema of a database, depicting the data tables, the data columns of those tables, and the relationships between the tables.      | presents a partial PDM for the university – you know that it isn’t complete by the fact that the Seminar table includes foreign keys to tables that aren’t shown, and quite frankly it’s obvious that many domain concepts such as course and professor are clearly not modeled. All but one of the boxes represent tables, the one exception is UniversityDB which lists the stored procedures implemented within the database. Because the diagram is given the stereo type Physical Data Model you know that the class boxes represent tables, without the diagram stereotype I would have needed to use the stereotype Table on each table.Relationships between tables are modeled using standard UML notation, although not shown in the example it would be reasonable to model composition and inheritance relationships between tables. Relationships are implemented via the use of keys (more on this below). Figure 1. A partial PDM for the university. When you are physical data modeling the following tasks are performed in an iterative manner: * Identify tables. Tables are the database equivalent of classes; data is stored in physical tables. As you can see in Figure 1 the university has a Student table to store student data, a Course table to store course data, and so on.Figure 1 uses a UML-based notation (this is a publicly defined profile which anyone can provide input into). If you have a class model in place a good start is to do a one-to-one mapping of your classes to data tables, an approach that works well in â€Å"greenfield† environments where you have the luxury of designing your database schema from scratch. Because this rarely happens in practice you need to be prepared to be constrained by one or more legacy database schemas which you will then need to map your classes to.In these situations it is unlikely that you will need to do much data modeling, you will simply need to learn to live with the existing data sources, but you will need to be able to read and understand existing models. In some cases you may need to perform legacy data analysis and model the existing schema before you can start working with it. * Normalize tables. Data normalization is a process in which data attributes within a data model are organized to increase the cohesion of tables and to reduce the coupling between tables. The fundamental goal is to ensure that data is stored in one and only one place.This is an important consideration for applic ation developers because it is incredibly difficult to stores objects in a relational database if a data attribute is stored in several places. The tables in Figure 1 are in third normal form (3NF). * Identify columns. A column is the database equivalent of an attribute, and each table will have one or more columns. For example, the Student table has attributes such as FirstName and StudentNumber. Unlike attributes in classes, which can either be primitive types or other objects, a column may only be a primitive type such as a char (a string), an int (integer), or a float. Identify stored procedures. A stored procedure is conceptually similar to a global method implemented by the database. In Figure 1 you see that stored procedures such as averageMark() and studentsEnrolled() are modeled as operations of the class UniversityDB. These stored procedures implement code that work with data stored in the database, in this case they calculate the average mark of a student and count the nu mber of students enrolled in a given seminar respectively.Although some of these stored procedures clearly act on data contained in a single table they are not modeled as part of the table (along the lines of methods being part of classes). Instead, because stored procedures are a part of the overall database and not a single table, they are modeled as part of a class with the name of the database. * Apply naming conventions. Your organization should have standards and guidelines applicable to data modeling, and if not you should lobby to have some put in place.As always, you should follow AM’s practice of Apply Modeling Standards. * Identify relationships. There are relationships between tables just like there are relationships between classes. The advice presented relationships in UML class diagrams applies. * Apply data model patterns. Some data modelers will apply common data model patterns, David Hay’s (1996) book Data Model Patterns is the best reference on the s ubject. Data model patterns are conceptually closest to analysis patterns because they describe solutions to common domain issues.Hay’s book is a very good reference for anyone involved in analysis-level modeling, even when you’re taking an object approach instead of a data approach because his patterns model business structures from a wide variety of business domains. * Assign keys. A key is one or more data attributes that uniquely identify a row in a table. A key that is two or more attributes is called a composite key. A primary key is the preferred key for an entity type whereas an alternate key (also known as a secondary key) is an alternative way to access rows within a table.In a physical database a key would be formed of one or more table columns whose value(s) uniquely identifies a row within a relational table. Primary keys are indicated using the stereotype and foreign keys via . Read here for more about keys. Although similar notation is used it is interes ting to note the differences between the PDM of Figure 21 and the UML class diagram from which is ti based: 1. Keys. Where it is common practice to not model scaffolding properties on class models it is common to model keys (the data equivalent of scaffolding). 2. Visibility. Visibility isn’t modeled for columns because they’re all public.However, because most databases support access control rights you may want to model them using UML constraints, UML notes, or as business rules. Similarly stored procedures are also public so they aren’t modeled either. 3. No many-to-many associations. Relational databases are unable to natively support many-to-many associations, unlike objects, and as a result you need to resolve them via the addition of an associative table. The closest thing to an associative table in is WaitList which was introduced to resolve the on waiting list many-to-many association depicted in the class diagram.A pure associative table is comprised of the primary key columns of the two tables which it maintains the relationship between, in this case StudentNumber from Student and SeminarOID from Seminar. Notice how in WaitList these columns have both a PK and an FK stereotype because they make up the primary key of WaitList while at the same time are foreign keys to the other two tables. WaitList isn’t truly an associative table because it contains non-key columns, in this case the Added column which is used to ensure that the first people on the waiting list are the ones that are given the opportunity to enroll if a seat becomes available.Had WaitList been a pure associative table I would have applied the associative table stereotype to it. Logical Versus Physical Database Modeling * March 14, 2001 * By Developer. com Staff * Bio  » * Send Email  » * More Articles  » After all business requirements have been gathered for a proposed database, they must be modeled. Models are created to visually represent the propose d database so that business requirements can easily be associated with database objects to ensure that all requirements have been completely and accurately gathered.Different types of diagrams are typically produced to illustrate the business processes, rules, entities, and organizational units that have been identified. These diagrams often include entity relationship diagrams, process flow diagrams, and server model diagrams. An entity relationship diagram (ERD) represents the entities, or groups of information, and their relationships maintained for a business. Process flow diagrams represent business processes and the flow of data between different processes and entities that have been defined.Server model diagrams represent a detailed picture of the database as being transformed from the business model into a relational database with tables, columns, and constraints. Basically, data modeling serves as a link between business needs and system requirements. Two types of data mode ling are as follows: * Logical modeling * Physical modeling If you are going to be working with databases, then it is important to understand the difference between logical and physical modeling, and how they relate to one another.Logical and physical modeling are described in more detail in the following subsections. * Post a comment * Email Article * Print Article * Share Articles Logical Modeling Logical modeling deals with gathering business requirements and converting those requirements into a model. The logical model revolves around the needs of the business, not the database, although the needs of the business are used to establish the needs of the database. Logical modeling involves gathering information about business processes, business entities (categories of data), and organizational units.After this information is gathered, diagrams and reports are produced including entity relationship diagrams, business process diagrams, and eventually process flow diagrams. The diagr ams produced should show the processes and data that exists, as well as the relationships between business processes and data. Logical modeling should accurately render a visual representation of the activities and data relevant to a particular business. Note| Logical modeling affects not only the direction of database design, but also indirectly affects the performance and administration of an implemented database.When time is invested performing logical modeling, more options become available for planning the design of the physical database. | The diagrams and documentation generated during logical modeling is used to determine whether the requirements of the business have been completely gathered. Management, developers, and end users alike review these diagrams and documentation to determine if more work is required before physical modeling commences. Typical deliverables of logical modeling include * Entity relationship diagrams An Entity Relationship Diagram is also referred t o as an analysis ERD.The point of the initial ERD is to provide the development team with a picture of the different categories of data for the business, as well as how these categories of data are related to one another. * Business process diagrams The process model illustrates all the parent and child processes that are performed by individuals within a company. The process model gives the development team an idea of how data moves within the organization. Because process models illustrate the activities of individuals in the company, the process model can be used to determine how a database application interface is design. * User feedback documentationPhysical Modeling Physical modeling involves the actual design of a database according to the requirements that were established during logical modeling. Logical modeling mainly involves gathering the requirements of the business, with the latter part of logical modeling directed toward the goals and requirements of the database. Ph ysical modeling deals with the conversion of the logical, or business model, into a relational database model. When physical modeling occurs, objects are being defined at the schema level. A schema is a group of related objects in a database. A database design effort is normally associated with one schema.During physical modeling, objects such as tables and columns are created based on entities and attributes that were defined during logical modeling. Constraints are also defined, including primary keys, foreign keys, other unique keys, and check constraints. Views can be created from database tables to summarize data or to simply provide the user with another perspective of certain data. Other objects such as indexes and snapshots can also be defined during physical modeling. Physical modeling is when all the pieces come together to complete the process of defining a database for a business.Physical modeling is database software specific, meaning that the objects defined during phy sical modeling can vary depending on the relational database software being used. For example, most relational database systems have variations with the way data types are represented and the way data is stored, although basic data types are conceptually the same among different implementations. Additionally, some database systems have objects that are not available in other database systems. Implementation of the Physical Model| The implementation of the physical model is dependent on the hardware and software being used by the company.The hardware can determine what type of software can be used because software is normally developed according to common hardware and operating system platforms. Some database software might only be available for Windows NT systems, whereas other software products such as Oracle are available on a wider range of operating system platforms, such as UNIX. The available hardware is also important during the implementation of the physical model because da ta is physically distributed onto one or more physical disk drives. Normally, the more physical drives available, the better the performance of the database after the implementation.Some software products now are Java-based and can run on virtually any platform. Typically, the decisions to use particular hardware, operating system platforms, and database software are made in conjunction with one another. | A logical data model describes your model entities and how they relate to each other. A physical data model describes each entity in detail, including information about how you would implement the model using a particular (database) product. In a logical model describing a person in a family tree, each person node would have attributes such as name(s), date of birth, place of birth, etc.The logical diagram would also show some kind of unique attribute or combination of attributes called a primary key that describes exactly one entry (a row in SQL) within this entity. The physical model for the person would contain implementation details. These details are things like data types, indexes, constraints, etc. The logical and physical model serve two different, but related purposes. A logical model is a way to draw your mental roadmap from a problem specification to an entity-based storage system.The user (problem owner) must understand and approve the logical model. A physical model is the roadmap from the logical model to the hardware. The developer (software owner) must understand and use the physical model. ERD Consider a hospital: Patients are treated in a single ward by the doctors assigned to them. Usually each patient will be assigned a single doctor, but in rare cases they will have two. Heathcare assistants also attend to the patients, a number of these are associated with each ward. Initially the system will be concerned solely with drug treatment.Each patient is required to take a variety of drugs a certain number of times per day and for varying leng ths of time. The system must record details concerning patient treatment and staff payment. Some staff are paid part time and doctors and care assistants work varying amounts of overtime at varying rates (subject to grade). The system will also need to track what treatments are required for which patients and when and it should be capable of calculating the cost of treatment per week for each patient (though it is currently unclear to what use this information will be put).
