What Is a Data Warehouse

Question 1 What is a data warehouse? What problems does it solve for a business? A data warehouse is a place where data is stored for archival purpose, analysis purpose. Usually a data warehouse is either a single computer or many computers servers tied together to create one giant computer systems. Data warehouse solve a lot of problems to companies as it helps to structure files and avoid unnecessary duplication of data.Data warehouse also allows to easily updating data and encourages management to regard data as a resource that must be properly managed just as any other resources. Question1B What do you see as the benefits of using a web-like browser to access information from a data warehouse? The benefits of using a web browser to access information from a data warehouse is that it allows users to have access to different search engines and opens up different links with the relevance key search. Some results will be more complete than others as they have different ways of indexi ng websites.Using a web browser to access information from a data warehouse is also useful as the links give you access to images and videos which interact users but can also slow down the logon level of speed operations meaning that the data warehouse is accessed at a fast speed.

Here are the advantages of these two very competitive companies in the industry of enterprise application software reported by Eweek[3]. Oracle advantages |Control of the Oracle database | |Without data, enterprise applications are little more than empty containers.As the Oracle database platform evolves, it is | |becoming the data management system for enterprise applications. | | | |More open environment | |Oracle has done a better job of embracing Web- and Java-based application development paradigms that are familiar to a broader| |number of developers. | | |Customers relationship management | |Due to its acquisitions of Siebel and PeopleSoft, Oracle has a deeper knowledge of business processes, driven more often than | |not by front-end CRM (customer relationship management) applications. | | | |Middleware | |Oracle isnt that much better than SAP in this category, but at least Oracle has recognized its weakness in the middleware area| |enough to try and acquire BEA. | | |Mid market channel | |Oracle has a stronger history in the channel than SAP, and, as such, has a better ability to leverage third-party solution | |providers in the small and midsize business market. | | | |Flexibility | |Oracle is a little more flexible in its approach to the business processes it will support, compared with the more | |hierarchical SAP model. | | |Global development Team | |Oracle development teams work together around the globe with relatively equal levels of autonomy. | | | |More third party application | |Years of working with ISVs on its database have created a stronger Oracle ecosystem. | | |Stronger OEM par tnership | |The Oracle database is a critical piece of enterprise software driving server sales for Dell and Hewlett-Packard (and making | |the latter companys sales force an extension | SAP advantages Legion of consultants | |A large army’s worth of business consultants owe their professional existence to SAP and help keep SAP the market leader. | | | |CIO loyalty | |Many CIO’s3 have invested millions of dollars in SAP and have staked their careers on its continued success. | | |Partnership with IBM | |IBM is probably one of the largest resellers of SAP software, on top of DB2 databases. | | | |Partnership with Microsoft | |Although SAP has ambitions in the SMB space in which Microsoft sells its own applications, a marriage of convenience results | |in a lot of Microsoft Office-to-SAP enterprise application work. | | |Open source | |Although SAP would balk at the idea of open-source application software, it provides tons of resources for the development of | |open-sou rce infrastructure software—making more money available for SAP software. | | |Business Process Integration | |Years of work in this area have resulted in a depth of expertise that is difficult to replicate. | | | |Global Footprint | |SAP has extended its enterprise application customer base around the world. | | |German Engineering | |Although it is sometimes seen as overly rigid, a reputation for attention to detail works in SAPs overall favor. | | | |Vertical market penetration | |Compared with Oracle, SAP has had more time to gain expertise across a broader array of industries. A recent Forrester research paper[4] found that Oracle has a strong middleware platform and better support of open standard and as such it is the right choice for customers who rely heavily on custom development in conjunction with packaged applications. The reporters Wang and Rymer asserted that companies in the high-tech manufacturing market segment would likely be better off with Oracle while co mpanies in the pharmaceutical and utilities industries would be more likely to choose SAP.In the light of this report my choice between theses systems will be based on the targeted market segment, in other words I will select the vendor that best suit my business activity. So therefore, I will select Oracle enterprise application if my company focuses on high-tech or with heavy reliability on custom development in conjunction with packaged applications. My choice in the other case will be to go for SAP if my business is found in the utilities industries or pharmaceutics. Making these choices will surely enable great customers satisfaction since they provide employees with the best equipments to serve these customers.Question3 Week 4 Lecture summary relating to: Data base models A data base model is a theory or specification describing how a data base is structured and used . several models have been suggested: The Hierarchal model is organized in to a tree like structure aiming to k eep data in an organized manner. This structure allows one relationship between two types of data i. e the parent child relationship, the child may have only one parent but the parent can have many children’s. The Network model organizes data using two fundamental records and sets.In other words the network model allows a many to many relationship meaning that the program maintains a current position and navigates fron one record to another by following relationships in which the record participates records can also be located b supplying key values. ( we have seen that most data bases used on man frame and minicomputer are based on the network or the hierarchal model. Relational model 3 key terms are widely used in the relational data base model these are relations , attributes and domain. A relation is theh colum and rows the named colums of the relations are called attributes and the domain is the set of values.The relational model was introduced as a way to make data base management system more independent. The structure of the relational model is a table where rows and columns of the tables are related. Database Development Entity modeling Entity relationship diagrams and entity relationship model illustrate the correlation and its nature between entities. The entities identifies the needs of the business and holds information of it all, with this method the relationship may be one to one or one to many. There are diverse benefits to the entity relationship modeling as it gives a specified picture of the current and requested system data.Normalization Normalization is the procedure of removing duplication of data. Normalization is also the process of verifying by making sure that there are no problems when updating the database and the operations on the various relations will not lead to conflicting and incorrect data. Part 2 Question1 (iii) What is the role of entity-relationship diagram and Normalization in database? Normalization and ERM are use ful techniques for data management because normalization is the process of organizing data to minimize duplication, it usally divides a database into two or more tables defining relationships between the tables.The objective of normalization is to isolate data so that additions, deletions, and modifications of a field can be made in just one table and then spread through the rest of the data base via the defined relationships. I. e the customers number is related to its matching customers name and matching customer order. Therefore ERM and Normalization techniques ensure that data is well organized so that when updating some data you face no duplications or error. Data modeling is the process of creating a logical representation of the structure of a data base because it provides a unified view of data which is independent of any model.

Silent Night

The night was silent. The half moon gazed down benevolently on the city, alone in a starless stretch of black sky. The streets were empty, and all that reached out into the shadowy darkness were the street lamps, placed so methodically and evenly it made them seem more significant than they really were. Near one of these lamps, on a bench, was an ancient man, his hair grey, his face was warped with deep wrinkles, a pair of round rimmed spectacles perched on his nose. His dull eyes, seeming to be staring into nothingness, peered sadly through the lenses.He slowly unlatched the case on his lap and reverently lifted the saxophone from its place, and is it opened, the weak yet mystifying golden glow emerged from it, only visible from the slight glimmer of the street lamps. The man pressed the mouth piece to his lips, and in a moment, music filled the night. The smooth, deep resonating tones of the saxophone echoed through the stillness. Its strong voice sang a melancholic requiem. The in strument was singing of times long past, of memories half forgotten, love once had, life at its peak and decline.The sounds resonated through the empty streets, reaching out in vain. The man stood as the song reached the climax, and as he did, the emotions that were resonating so beautifully seemed only to be amplified, this was pure expression from the soul; unprepared, and unrestrained. The man closed his eyes and arched backwards as the saxophone bellowed its elegy. Untainted emotions, pure and true, resounded from the notes, a defiant dirge amidst the sadness and grief of loss and solitude. Then the night was silent again.His performance was applauded by the silence and the dark, and it was deafening. The elderly man breathed heavily, perspiration dampening his dull grey hair. He fell back on the bench and before long, began absently polishing the saxophone. His audience, the darkness, seemed to evaporate into the night, and he was left more alone than before. He heaved a sigh a nd reached for the case. Suddenly, sound had blessed the night. The rich sound of a saxophone reverberated from the darkness. The man started and rose from the bench, the rich melody wafting towards him like an old friend.He twisted and swivelled, his eyes brightened as he searched for the player. By a street lamp, was a silhouette of a person with a saxophone, the musician sitting by the lamp, not close enough to be illuminated and not far enough to be hidden, but there was no reason for the mysterious figure to be identified. The man immediately recognised the musician’s skill, but there was a sense of incompletion in the tune, and although the tune itself sounded familiar, but he couldn’t recognise it. Read also  Summary : Love Is Never SilentIt was when the piece reached the first chorus that he finally did, and understood. He smiled warmly, his eyes glittered, and he raised his mouthpiece to his lips again. He accepted the invitation, and the music was complete. It was a song of fulfilment, contentment, of joy and harmony, the instruments’ eulogy of shared emotion and elation. The man revelled in the performance, and he knew silence would not meet him at the end of this one. The rich voices of the saxophones intertwined and coalesced. It was a glorious anthem that purged the night of silence.

Contemporary Women in Visual Art Essay Example | Topics and Well Written Essays - 1250 words

Contemporary Women in Visual Art - Essay Example However, there is increasing war for fair representation of women in visual art. In the article â€Å"China’s Female Artists Quietly Emerge† by Cotter, this issue is deeply discussed. This paper presents a critical analysis of this article by evaluating its approach, relevant insights, authenticity, viewpoints, and authoritativeness among others. The place of women has been greatly contested in the recent times. As the article presents it, women in China have had no any chance in Chinese visual art for a long time despite their profound talents in different fields of visual arts. Having reached a breaking point, they are presenting their anger by openly defying social norms that enclose men into the world of arts. Cotter uses a rich mix of literature techniques to present her point of view. The article begins with a very interesting and captivating introduction that directly catches the mind of the reader. From the word go, the issue discussed within the article is intr oduced. Xiao Lu demonstrates her anger and protest in a national art gallery by shooting at a mirrored sculpture. It is actually ironical that this was the first Chinese government sponsored exhibition and did not address the role of women in visual art. What she had done was a symbolic explosion that expressed protest among the international art enthusiasts and critics. Indeed Li Xianting, an art critic, criticized the incident as a precursor to the infamous Tiananmen Square protests of 1989. The big issue presented by the article is the position given to women in contemporary art particularly in china. Women, however talented, are rarely given a chance to display their artistic talent, especially in visual arts. Men always take the first preference. Artwork done by women is a rare commodity to find even in large and modernized social settings such as Beijing. Although the article does not have a reference list, most of the information can be traced back to the original source. For instance, the event on the article correlates with later happenings as claimed in the article. A follow up on Tiananmen Square protests of 1989 shows that Xiao Lu protest event at the national gallery could indeed have been a precursor of the Tiananmen Square protests. Further investigation proves that Li Xianting is indeed claimed to be a Godfather of Chinese contemporary avant-garde art. Yin Xuizhen is indeed a contemporary art enthusiast as claimed in the article. These plus other examples prove that though the article does not have a reference list, the information contained therein is authentic and trustworthy. However, the failure to include references in the article has given the author a great deal of flexibility in expressing the main ideas. The main idea is developed from a neutral point without much influence from works of other authors. It can be claimed that the article is written in an idealistic point of view. The article takes on a woman character and develops her c ontribution to the agenda of contemporary visual artwork. The contributions of contemporary visual artists, such as Ms. Xiao, Lin Tianmiao, Yin Xuizhen, and Lu Qing, have been well elaborated, and this expresses the viewpoint clearly. The article presents the issue of contemporary artists in a time in history when gender equality and affirmative actions have received heightened attention. Interestingly, Beijing happens to be a global symbol regarding representation of women issues. The fourth world conference on women took

The Ontological and Economic Trinity Essay Example | Topics and Well Written Essays - 3000 words

The Ontological and Economic Trinity - Essay Example The three persons are said to be equal in nature and in their attributes. By saying that the three persons are equal in attributes, it means that they are omniscience, they are omnipresent and they are holy. It is acceptable among all Christians across the world that the three persons do not change, they are holy and that they are divine. This state of the three persons having equal attributes and being equal in nature is referred to as the Ontological Trinity2.The word Ontology refers to the study of essence. As a result, the Ontological Trinity can also be referred to as the Essential Trinity or the Immanent Trinity. On the other hand, these three persons are said to differ in the manner with which they work and also the way they associate with the world and with each other. Each of them has varying roles in how they relate to the world. Their roles within the Godhead are also different. Each of them has their own activities and they perform them independently. This difference in h ow these persons relate to each other and to the world is referred to as the Economic Trinity. The name economic has been derived from the Greek word oikonomikos which means management of activities3. Therefore, the three persons manage their activities differently. The Ontological Trinity and the Economic Trinity are usually confusing among many Christians This makes it difficult for Christians to understand the exact nature of God Himself. It is not easy for a typical Christian to distinguish between the Ontological Trinity and the Economic Trinity. In addition, it is not easy for Christians to figure out the relationship between the two. This makes the understanding of God and how He works to become a mystery to many. Understanding these two issues can be of much importance to Christians in that they will understand how God works Project Summary The purpose of this project is to conduct a research that will help Christians understand the three persons in Trinity. They will be abl e to distinguish between the Economic Trinity and the Ontological Trinity. Having understood this, Christians will be in a better position to understand the Existence of God and also understand how God works in through the three persons in trinity (i.e.) the Father, the Son and the Holy Spirit. In this project, I hope to bring out a clear distinction between Ontological Trinity and the Economic Trinity. I also hope to outline and evaluate how the three persons relate to each other and how they work together. Once I am able to achieve this, the project will have achieved its mission which is to enable Christians understand God in a better way. To accomplish this purpose, I will do extensive research from academic literature and compile a report at the end of the research that gives relevant answer to the research question. History of the Doctrine of the Trinity The root of the doctrine of the Trinity can be traced from as early as the first century. The doctrine has taken centuries t o develop leading to the modern definition that is the subject of this paper. The word "Trinity" is not seen in the New Testament and neither is the doctrine explicitly taught in the scriptures4. However, we can trace the foundations of the concept of the Trinity from the New Testament, particularly from the Gospel of John, which arguably is one of the latest and one of the most theologically developed books of the New Testament. Mentions of the Trinitarian beliefs also can be seen in the extra-biblical teachings of theological writers

A Literary review of William Shakespeare's play Othello Essay

A Literary review of William Shakespeare's play Othello - Essay Example He is admirable in many ways, and seems to have led a blameless life before the meddling of Iago in his relationship with his wife Desdemona. Despite all his heroic attributes, there is one thing that proves to be his downfall: Othello cannot free himself from the prejudice against his religion and race which he faces, and this makes him over-sensitive to criticism and much too hasty in defending his honor. Iago describes Othello at the very start of the play as â€Å"The Moor† (1.1.39) and Roderigo calls him â€Å"the-thick lips† (1.1.65) before we have had a chance even to meet him, and this sets the scene of a society which judges people by the color of their skin. In Shakespearean times English audiences would very rarely have seen a black man, and so this element of difference would have been something exotic and perhaps also a little shocking to them too. It is clear that Iago does not like Othello. The men of Venice suspect that he has used witchcraft, which is n ot permissible for Christian citizens and a Senator asks â€Å"Did you by indirect and forced courses/ Subdue and poison this young maid’s affections/ Or came it by request and such fair question/ As soul to soul affordeth? (1.3.111-113) Against such a scandalous suggestion, Othello responds with an answer that would stresses his own bravery and her own freely given love for him: â€Å"She loved me for the dangers I had passed,/ And I loved her that she did pity them. This only is the witchcraft I have used.† (1.3.166-168) Othello wants to be like the rest of them, successful in his job and happy with his wife, whom he loves. Unfortunately, this is precisely what Iago resents, because Iago is jealous and thinks that people who are not Venetians and Christians should not enjoy the benefits of a noble position. When Iago sets up his plan to trick Othello by pretending that Desdemona is unfaithful, he is targeting the point where Othello is most weak. His pure and beauti ful wife is, to Othello, the most precious thing in his life. For Othello, Desdemona’s love signifies acceptance in this new world, and her conventional innocence and beauty are the qualities that he cannot have himself, because of his appearance and background. Through her, he feels at peace with the and successful at last after many years of hardship. This is a kind of pride, but most people would forgive him for this because he is a faithful husband and dutiful servant of the court. One of the interesting aspects of the play is the fact that Othello believes Iago’s accusations, and does not trust in the faithfulness of Desdemona. His reaction to the accusation is very extreme and he can hardly speak before falling down in a trance. (4.1.42) His honesty and truthfulness are no use to him in the face of such deceit, and the supposed knowledge completely overwhelms him so that all he can think of is revenge. The irony of the play is that it is his high moral standards, and his attachment to honor and duty that make him so intolerant of supposed infidelity. At the end of the play, when Desdemona is dead and Othello is about to kill himself he tries to explain this paradox to himself and to the audience. He wants to be remembered as he was, a man of high honor but also one who made a dreadful and violent mistake: â€Å"An honourable murderer, if you will,/ For naught I did in hate, but all in honour.†

Supply Chain Management Essay Example | Topics and Well Written Essays - 1500 words - 9

Supply Chain Management - Essay Example so allow them to supply to the market as quickly and precisely as possible in order to meet the actual demand without being able to consider maintaining a high inventory level. When there is high inventory, there is also high linked up cost with it. Thus, the prevailing structural program of Dell with respect to its recent supply chain strategy ensures a great way of generation of profit as the entire activity minimizes the loss of market opportunity. In other words, the ability of Dell to forecast demand allows it to provide the essential supply to its target marketplace. In order to do this, the company relies heavily on information by maintaining constant flow of data through two information loops (Oracle, 2013). This means that the flow of information should take place between customers and Dell sales team and the other one takes place among sales, procurement and suppliers (Oracle, 2013). Supply chain could be defined as a set of two or more entities involved in the upstream and downstream flow of products, services, finances and information from the source to a consumer (Overbeck, 2009, p.17). It is upstream from the point of view of consumer and the other way around for the source. This definition gives us the idea that the flow of products, services and information is sequential, which means that the output of the first level is the input of the next level. However, due to the existing complexity of relationships involved in the supply chain today, ‘supply network’ was coined (Overbeck, 2009, p.17). According to Hieber (2002), the nature of supply chain is unique (p.130). This is because there is complexity involved within the flow of goods and information between the linked entities in the supply chain. This according to him would require a changing set of priorities from time to time, requiring a high level of responsiveness on the part of the organisation. According to Jones and Tilley (2007), supply chains and management have become potential

Australian law Essay Example | Topics and Well Written Essays - 1000 words

Australian law - Essay Example If a professional adviser is found to knowingly having provided or failed to provide information that exposes the advisee to incur any losses or damages on their part, this considered to be a breach of duty. All professionals are generally held to an established and reasonable standard of basic care and professionalism. Professionals are generally required to have the necessary learning and skill that is seen to be commonly processed by members who happen to be held in good standing within their basic profession.2 However, any lack of the proper degree of training, failure by the professional to attempt to follow up on a client’s progress, failure to remain appropriately conversant with any new emerging discoveries in the field, or failure to refer to a specialist in the event that it proves to be necessary can all be seen to constitute of negligence.3 As exemplified in the line of reasoning followed in the Hedley Byrne ruling, when an adviser communicates information to an ad visee in order that the information might be used for a generally described or particularly specified purpose, and the advisee acts on this advice to his detriment, the adviser is found to fundamentally be guilty of negligence.4 Effects of Donoghue V Stevenson (1932) A decision by the British house of commons in 1932 concerning the alleged presence of a snail inside a ginger beer bottle is commonly perceived to be the best known judgment in the entire common law world. It is widely regarded as the primary foundation law of negligence throughout the entire British Commonwealth.5 Although the ruling of Donoghue V Stevenson (1932), was initially mostly applied to judgments pertaining to manufacturers and the duty of care that they happened to owe the various consumers of their products it was eventually seen to have wider relevance beyond manufacturer liability. In the ruling, Atkins was seen to assert that a duty to exercise case was actually owed to all persons who might be directly affected by one’s actions or omissions that happen to be called in question.6 This is seen to critically affect the liability of all professional advisers as in their event that they provide questionable information that eventually proves to be detrimental to the advisee, they are then effectively held viable for court action. The Effects of Hedley Byrne v. Heller (1963) The Hedley Byrne v. Heller (1963) greatly impacted the overall liability of professional advisers as it was the first decision to recognize the possibility of there being a liability for want can be perceived to be purely economic loss that is not dependent on there being a contractual relationship, for negligent statements. This was seen to affect advisers as any information that they may happen to give while not bound to any contractual agreement can also be seen to create duty of care as it might be relied upon by the advisee in determining whether to enter into a contract.7 Recent Developments in Australi an High Court There have been a number of recent developments in Australia pertaining to the case of professional negligence, in Astley v Austrust Ltd,
