Rdms. phase 1 db2 - Essay Example The second phase focuses on the design of the database model that will support company operations and objectives. In the process of database design, concentration must be placed on the data characteristics required to build the database model. Two views of the data within the system are available the business view of data and the designers' view. RDBLC's second phase also includes data definition. It is also important to note thatthe database design is not a sequential process it is rather an iterative process with continuous feedback. In the conceptual design phase, an abstract structure is created that represents real-world objects in the most realistic way possible. The conceptual model must represent a clear understanding of the business and its functional areas and is software and hardware independent. ii) Entity relationship modeling and normalization (The ER model serves to be a communication tool between technical and non-technical individuals as well as a design blueprint. During normalization the dependencies are checked and data anomalies removed) Logical design is used to translate the conceptual design into the internal model (database schema) for a selected database management system. Therefore, the logical design is obviously software-dependent. III. Physical Design Physical design is the process of selecting the data storage access characteristics of the database. These characteristics are actually the types of devices supported by the hardware, the system, and the DBMS. Therefore the physical design is hardware dependant. It affects not only the location of the data in the storage device(s) but also the performance of the system. 3. Implementation and Loading The relational database and its interfaces are created according to the specification of a logical schema. A new database implementation requires the creation of special storage-related blocks for the placement of end-user tables. During the implementation and loading phase, the security, performance, integrity, backup and recovery, standards, and control issues must also be addressed. 4. Testing Once the data have been loaded into the database, the DBA tests and fine-tunes the database for performance, integrity, concurrent access, and security constraints. The testing and evaluation phase occurs in parallel with applications programming. 5. Operation Once the database has passed the test phase, it is considered to be operational. On the whole all the components the database, its management, its users, and its application programs are in place at this time and represent a complete information system. 6. Maintenance The maintenance phase starts as soon the database is implemented. The database

Miller associates Essay Example for Free

Miller associates Essay Miller uses language carefully throughout the play to create various atmospheres. In Proctors meeting with Abigail, emotions were running high, and there was a certain amount of fission and sexual chemistry between them. The atmosphere here was passionate, angry and lustful. This is a direct contrast to the start of act two, as Proctor talks with his wife, Elizabeth. The atmosphere is cold and formal. There is no chemistry between the two, and we begin to understand why Proctor was so tempted by Abigail. It is clear to see there is a spark between them, whereas his relationship with Elizabeth is sterile and dull. Miller associates Proctor with fire and burning he burned with lust for Abigail, and then with guilt. This imagery makes us think of danger, the devil and witchcraft. The connotations of fire, especially in a society such as Salem are of hell and burning in hell for eternity. This also links in with the title; Miller chose the title of The Crucible to demonstrate Proctors metaphorical journey. Proctor is like the metals that go in the crucible to be purged of all impurities. Proctor comes out at the end with no impurities. Proctor says, its winter in here yet Elizabeth. This quote suggests their relationship is still not mended, and shows us just how cold it really is, not only in their home, but their relationship. Winter is an effective metaphor because it demonstrates Elizabeths coldness towards Proctor. The Proctors are struggling to heal a rift in their marriage and this is portrayed by Elizabeths coldness, silence and Proctors fiery outbursts. Proctor also compares his house to a court; I cannot speak but I am doubted, every moment judged for lies, as though I come into a court when I come into this house. Proctor still hasnt regained Elizabeths trust and is frustrated by her scepticism. However, he is also angry with himself, as he knows that he has given her a good reason to act this way, and he cant expect her not to, as it was his wrong doing that is causing her to behave in this manner. Proctor feels that Elizabeth judges him, Let you look sometimes for the goodness in me, and judge me not. Elizabeth says it is Proctor that judges himself, The magistrate sits in your heart that judges you. She understands how guilty he feels, but knows Proctor must atone before he can resolve his marriage and regain his self respect. He considers himself a fraud for betraying his own vision of decent conduct. Proctor is disappointed in himself for not being strong enough to resist temptation and for betraying his wife, and he regrets this deeply. The only way Proctor can make up for his sins is to atone, until then he is tortured by his actions. Elizabeth is the only one who understands his need for atonement. At first Proctor is reluctant to expose the truth about Abigail. This shows us he is afraid to hurt Abigail and possibly expose himself as a lecher, but he is also afraid of embarrassing his wife. It is only at the end of act two when Elizabeth is under threat that Proctor knows he must tell the truth. Proctor feels guilty when Elizabeth is accused because he knows it is Abigails way of getting back at them; getting back at John for leaving her, and getting back at Elizabeth for having what she wants, and for dismissing her from working in her home. Proctor must sacrifice his good name, which is one of his most prized possessions to save his wife. This shows us how much he truly loves Elizabeth, even though they have grown apart. They no longer have any chemistry between them, as John and Abigail do, but they have a strong bond, which is the basis of their relationship. Abigail desires vengeance against Elizabeth, because she sees Elizabeth as the only obstacle between her and Proctor. Elizabeths arrest is an opportunity for Proctor to atone his sins and wrong-doing, because he can come clean and confess his affair, and save Elizabeth, and rectify his marriage. In doing this, he also shows the court how sinful and bad Abigail really is. Until this point, all the people in the community, with the exception of the other young girls, has seen Abigail as a sweet, innocent girl, caught up in witchcraft. Proctors confession horrifies Abigail, as she realises that this could endanger her. Proctor is the only person who seems to see that the girls are making up these lies of witchcraft to save themselves from being whipped. Events have conspired against Proctor and the public crisis in Salem has become his own personal nightmare. His initial intention to save Elizabeth grows to a wider purpose, of saving his friends and exposing the corrupt authority and the girls lies and deceit. Parris tries to accuse Proctor of trying to overthrow the court, and this accusation only shows us that the court was purely biased and any defence was treated as an attack on the court. Proctor sacrifices his good name by admitting to the court his affair with Abigail, and at this point, we see that he has now become completely desperate, I beg you, sir, I beg you. He is so determined to save Elizabeth that he will beg the court and totally humiliate himself. This shows his sheer desperation and Proctor swallowing his pride for the sake of the community and the people he loves; this is his attempt to atone, and prove his love for Elizabeth. When asked if Proctor committed adultery Elizabeth ironically lies and says she has know knowledge of John being unfaithful. She lies to protect him and save his good name and reputation, even if it meant she as still accused. But, in doing this, she also protects Abigail, and her claims of witchcraft become more credible to the courts once again. This, gives us further sympathy for John, as he has thrown away his good name, and yet, it got him nowhere. Elizabeths denial, however, shows that despite Proctors affair, Proctor and Elizabeth are still deeply in love as they are both willing to sacrifice themselves for each other. This shows their relationship is strong but they just have problems communicating their feelings and the affair brought a barrier down between them. We also see here, where the obstacle between John and Abigail was Elizabeth, the obstacle between John and Elizabeth is Abigail, as it is because of her jealousy and accusations that Elizabeth is imprisoned. The consequences of Elizabeths only lie is that Proctor is accused of witchcraft and will hang unless he lies and confesses. The irony here is that if he tells the truth, the truth is seen as a lie, yet if he lies, the lie is seen as the truth. This seems to be the moral of the town throughout the play: Only those who lie survive. However, being a religious town, it is seen that liars will go to hell and be damned when they die. This is why the good, religious people of the community, such as Martha Corey and Rebecca Nurse, refuse to confess to witchcraft to save themselves. They refuse to sin for the sake of a lie. At the end of Act three, Proctor is accused of witchcraft, just as Miller, and many others, were accused of communism during the McCarthy witch hunts. The parallels between Proctor and Miller are the paranoia and mass hysteria that was surrounding them and the fear they felt. Neither Proctor nor Miller confessed, and neither would give names of their friends. Proctor is now is now in open conflict with the court. His friends rely on him and his life is in the balance. This scene has endeared us, the audience to him because we see his utter desperation and the way he will sacrifice himself for Elizabeth and the way he protects his friends. We sympathise with him because he has a tough decision to make, life or death, wrong or right. He is struggling with his morals too, as he cannot help his friends if he is dead, yet he doesnt have it in him to confess to a sin he hasnt committed.

Unrelated Incidents’ by Tom Leonard and Search for my Tongue by Sujata Bhatt :: English Literature

What does the way a person speaks tell us about the person? ‘Unrelated Incidents’ by Tom Leonard and ‘Search for my Tongue’ by Sujata Bhatt are two poems that give people an incite into how a person is perceived by others, by the way that they speak. ‘Unrelated Incidents’ is about how the BBC newsreaders all talking in Standard English and will not have a Scottish person reading the news because the viewers will not understand there accent, Tom Leonard views this as discrimination and shows his dislike to this attitude in his poem. ‘Search for my Tongue’ is about Sujata Bhatt’s personal experiences with learning another language and having to speak in a foreign tongue and forgetting about the mother tongue which is the original language. When Sujata thinks that she has finally lost her mother tongue she starts to hear it again in her dreams. The layout of the poem ‘Unrelated Incidents’ is set out in an unusual way because of the poem talking about the BBC newsreaders. When the newsreaders reads out the news they read it off of autocue and this is how the poem is set out. When first looking at ‘Unrelated Incidents’ it is difficult to read because of the spellings of the words. The poem is written phonetically and not in Standard English. Tom Leonard says in line 27-30 ‘this is me token yir right way a spellin.’ Leonard also uses colloquial which is slang he uses it in the last line with ‘belt up’ he does this to mock the way the news is read because of the poem being written as if it were the six clock news. This is different to ‘Search for my Tongue’ because Sujata Bhatt for 15 lines writes in English but then from line 16-29 writes in Gujarati which is her mother language, beneath this it also tells the reader how to read this language (which is spelt phonetically). The lines written in Gujarati is actually the first part of the poem written again and when you read it the first part sounds harsh and not very nice to read but when you read it for a second time in Gujarati it flows and is nice to read. In ‘Unrelated Incidents’ and ‘Search for my Tongue’ they either are cross or upset with themselves or with others around them. In the poem ‘Unrelated Incidents’ the Scottish man is angry for being rejected by the BBC just because of the way that he talks and because of his accent and in ‘Search for my Tongue’ she is upset with herself for not

Macroindividual Essay

I need to explain the uses, problem and critically examine the uses or problems with real life examples. Question 1 Briefly explain the uses of National Income Statistics. Comparison over Time According to Vengedasalam D. and Madhavan K. (2010), national income able to state the economy’s performance whether is progressing, stagnating or deteriorating on yearly basis from national income figures. For example like Singapore, their national income has improved steadily over the years which indicate that the country have a stable economy and high in productivity. As for economies in countries such as India, China, and Bangladesh are stagnating and should take action to increase their growth and development. However countries such as Vietnam, Cambodia, and some African countries have deteriorated in terms of economic performance. Comparisons between Countries Ali H. (1999) stated that we can differentiate the development and developing countries through national income. According to an international organization, OECD (Organization Economic Cooperation and Development) statistic, Singapore was the 13th richest country in the world. OECD is to tackle the country performance to estimate the country is developed or still developing. Countries such as Ethiopia, Myanmar, Bangladesh and most of the Asian states are the poorer nations. Measurement the Standard of Living According to Vengedasalam D. and Madhavan K. (2010), nationwide earnings information able to help us evaluate the quality lifestyle of individuals in different nations and the individuals residing in the same nations at different times. There is a correlation between national income and standard of living because when income is high, standards of living is high; when income is low, standards of living is low. For example countries such as United States, United Kingdom, Canada, and Australia have high national income and also high standards of living. However, as for the countries such as Ethiopia and Myanmar have low national income leads to low standards of living. Balance of Payment Ali H. (1999) stated that stability of transaction can be determine as the complete of expenses and invoices that a nation generates as result of transfer and trade worldwide with other nations. We can approximately calculate whether the nation will face lack or excess balance of transaction through the nationwide earnings data. There will be an output of forex from the nation and this will lead to disequilibrium in the complete amount of transaction if earnings paid overseas are far greater than earnings obtained overseas. National Planning According to Vengedasalam D. and Madhavan K. (2010), national planning also knows as planning of each of the countries which based on the national income statistic, the government will formulate its short term and long term economic planning. In this case, Karl E. Case and Ray C. Fair (2003) stated on the basis of present economic performance, the government will have to forecast future developments. This which if income increase, plans for the future will increase; same goes to if income decrease, plans for the future will decrease. This also important and why all the countries have to collate data on national income. Question 2 Discuss the problems involved in calculating the GNP per capita of an economy. Underground Economy O’Sullivan A. , Sheffrin S. M. , and Perez S. J. (2012) stated that one of the significant problems from measured GDP is so-called underground economy where transactions are not reported to official authorities. According to Lipsey (1998), some transactions are perfectly legal, but for the people do not report their income that they have generated it is because they wanted to avoid paying taxes. For example plumber who repairs pipes leakages in the toilet and only receive payment by cash which is to avoid taxes and these transactions are not recorded so they are excluded from GDP. According to Tucker I. B. (2008), some transaction such as illegal gambling, illegal drugs, illegal guns prostitution, and loan-shark are goods and services that meets every requirement for GDP but GDP does not include unreported criminals activities. Nonmarket Activities According to Lipsey (1998), dealings that do not take position in the structured industry are also being disregards by GDP. For illustrations like solutions that individuals do for themselves in their own houses because these solutions are not moved through markets; this is so GDP statisticians cannot evaluate them. Tucker I. B. (2008) stated nonmarket activities that are not transferred though the markets such as homemaker production, do-it-yourself activities, childcare services, and voluntary work. Problem of Illiteracy Vengedasalam D. and Madhavan K. 2010) stated that problem of illiteracy most happen in third world countries like Bangladesh, Indonesia, Myanmar, India, and many African nations which the people there do not know how to keep accounts of their productive activities. With this problem of illiteracy, the governments of these countries will have difficulties in getting information such as estimated value of home produced product. For example people there do not have knowledge on marketing and finance which makes them do not know the value of product they are selling. Problems of Expertise According to Vengedasalam D. nd Madhavan K. (2010), one of the major problems of developing countries is shortage of professionals. In order to measure the national income accurately, we need the professional services such as statisticians, analysts, programmers, researchers. With these professionals in the developing countries will be able to present the national income data accurately with less technical and human errors. For example if the country do not have programmer, they need to record the national income data in papers and there will be more human errors. Lack of Sophisticated Machinery Vengedasalam D. and Madhavan K. (2010) stated that technical aspect is as important as human factor. Technical aspect such as having sophisticated machinery is needed to compute data and information. For example, problems that developing countries like Indonesia and Peru are facing the problem of technical experts and technical equipment. There countries need this latest and advance machinery to compute massive volume of data. In the end, data that collected on national income need to be analyzed using sophisticated machinery regardless of which method is used. Question 3 Explain with examples whether you support its use as a measure of quality of life in a country. No, I do not support its uses as an evaluation of total well-being in a nation. The factors as follows: Problem of Illiteracy Third world countries like Bangladesh, Indonesia, Myanmar, India, and many African nation facing this problems in which the people there do not know how to keep accounts of their productive activities. For example, Memon G. R. (2007) stated Pakistan has one of the smallest expenses of details on the globe, and the smallest among nations of relative resources and public or financial conditions. With a per close relatives earnings of over $450 Pakistan has an older details amount of 49%, while both Vietnam and Local Indian native with less per close relatives earnings have details expenses of 94% and 52%, respectively (Human Development Middle, 1998). Knowledge is greater in places and in the areas of Sindh and Punjab, among the greater earnings group, and in men. Nonmarket Activities According to Shaheen S. , Sial M. H. , Awan M. S. (2011), woman’s option about contribution in work market is of crucial importance in determining living standard, dependency stress and saving design in homes. Women signify about half of the people in this country in Pakistan. But in Pakistan mostly female’s execute happens in non-market activities in the home or the informal market. In recent past women contribution in modern market activities has been increasing. Factors determining the profession of women are extremely complex. At the individual level female’s option to execute is topic to such factors as the availability to projects, knowledge level and skills. Underground Economy One of the problems from measured GDP is so-called underground economy where transactions are not reported to official authorities. According to Schneider F. and Enste D. H. (2000), the results from eight nations in African-american are revealed, among these, Nigeria and The red sea have the biggest subterranean financial systems with 76 % and 68 % of GDP; Mauritius has the tiniest subterranean economic system with 20 %. Implementing the forex requirement strategy, Tanzania had a subterranean economic system of 31 % (of GDP) in 1989–90, and Southern African-american, 9 % in 1989 to 1990. The position of the size the subterranean financial systems for the Africa nations is reinforced by identical results and historical proof from Pozo (1996); Lawrence Chickering and Muhamed Salahdine (1991); and Lubell (1991). Conclusion I have explained the uses and problems. I have also examined the problems with real life examples.

AB Thorsten Case Study Analysis

In my view, manufacture of XL-4 in Sweden is a well laid out plan and Mr. Ekstrom and his team has done good research and analysis of the project. However, I would not authorize the investment. To start with, the investment in Sweden will cost the company heavily as it will involve setting up a new factory at a whooping cost of Skr. 76.385 million.In making investments decisions, we must always consider all possible alternatives then come up with the most viable one. In this case for example, we have an option of expanding the Canadian plant which supplies the Swedish market to provide for the proposed increase in market share at a cost of only Skr. 7.183.The expansion would not only ensure minimal rise in the fixed costs but also save the company due to the economies of scale enjoyed by the Canadian plant. As compared to the five years that the company will take to recover its investments for the Swedish plant, upgrading the Canadian plant will only take 2.5 years to give the compan y a return on its investments.In addition, the company stands to benefit form the high internal rates of return in Canada which are set at 60% as opposed to the Canadian 15.7% rate of return (Torre, 1999). Incorporating the production of more XL-4 to supply the 400 tons demand in the Swedish market would therefore prove more viable as it will save more resources.The resources saved could actually be used for other purposes or be invested in projects that will bring forth higher returns within a shorter time such as investing in bonds and bank certificates. The investment in Sweden should therefore not be undertaken.According to Ekstrom and his team, the proposed project was going to be a major breakthrough for the company with a potential market of 800 tons of XL-4 in Sweden. Customer trial conducted using three major companies have revealed that indeed the technology of XL-4 can save the companies a great deal in terms of costs, material handling and fuel.Ekstrom and his team are c alling to the management to help in setting up a plant producing 400 tons of XL-4 each year at a cost of about Skr. 76.385 million in plant and machinery.Working capital of about Skr. 5.6 million will be required as working capital. Ekstrom states that the plant can recover 60% of its inventory costs from the taxable income as the Swedish law permits it. The plant's life after which it will have to be renovated to suit advancement in technology is given as seven years.By the end of the seven years, the Swedish plant should have reached a net present value of Skr. 15 million after taxes. The analysis is well performed using modern management tools and they are highly optimistic of all the figures presented.The analysis however does not include the sales projects in case the company may decide to expand to Europe and the rest of Scandinavia. On the question as to where the funds would come from, Ekstrom explained that funding could be obtained from borrowing in Swedish banks if the de mand surpassed 400 tons.The Canadian divisional management is against the investments. They give several reasons to support their arguments. Gichoud, the director of sales argues that the sales of 400 tons per year were far too optimistic citing from his experience in marketing (Torre, 1999).According to him, there is no way they can make 400 tons sales in Sweden alone while Roget's overall world market is only 600 tons. Director of manufacturing, Levanchy is also not very keen on the project saying that the manufacturing processes is very complicated for Sweden to undertake even with the presence of trained workers.The Canadian management insists that this is an expensive undertaking for the company taking up a lot of money which could have been saved if the production was done in Canada.They compare the returns and number of years taken to get a return on the investments. As opposed to Sweden which will use initial costs of Skr. 76.385, Canada would spend Skr. 7.183; get returns i n 2.5 years as opposed to Sweden's five years; get a higher rate of return on capital of 60% as compared to Sweden's 15%.The issues of uncertainty and market trends are ignored in estimating the demand of XL-4. Customer choice resulting from competition, increase in technology and changes in the markets is an important consideration before making an investment.In the event that a new product comes to the market before the seven years proposed by Ekstrom and his team are over, the division is likely to suffer losses from the huge investments. Take for example that the target 400 tons per year falls due to the changes in market or emergence of a competitor.The predicted plant's net value would be lower than Skr. 15 million. A 15% return cannot also be achieved. The management therefore ought to give an allowance for any changes in the market. This proposal takes the market as a constant playing ground which according to them will only change after seven years.
