...(SSC) provides information technology (IT) services and consulting, which include developmental solutions, IT integration, strengthening, analysis, design, and implementation (Apollo Group, 2004). SSC will submit a proposal to KFF that details the development processes of the FSP project. This paper is a technical article document that lists the project’s logical and physical models, which includes hardware, network, software, database, controls, and other development related tools. Logical and Physical Models Logical and physical models are representations of the key elements and processes of a software development. The logical model describes the processes, especially data, in as much detail as possible, without giving regard to how the system will be physically implemented. Logical data models include entities and relationships among them and how data flows from one process or entity to another. The physical model, on the other hand, delineates the physical implementation of the system, which answers how the logical model will be implemented physically. The physical model is a modified version of the logical model, intended particularly to work with a specific set of...

...Define user documentation Written or other visual information about an application system, how it works, and how to use it. (17) . User documentation refers to the documentation for a product or service provided to the end users. The user documentation is designed to assist end users to use the product or service. This is often referred to as user assistance. The user documentation is a part of the overall product delivered to the customer. The sections of a user manual often include: * A cover page * A title page and copyright page * A preface, containing details of related documents and information on how to navigate the user guide * A contents page * A guide on how to use at least the main functions of the system * A troubleshooting section detailing possible errors or problems that may occur, along with how to fix them * A FAQ (Frequently Asked Questions) * Where to find further help, and contact details * A glossary and, for larger documents, an index realized the importance of documentation many years ago when I joined an organization to head its IT function. The previous IT head had left the organization a couple of months ago. The managing director called me over and voiced his expectation. He told me that all ground work had been done for ordering new set of servers and application packages and that I should act upon it soon. I promised to take a look at the situation and revert with plans. However, when I sat in my department...

...Critically assess the claim that religious language is meaningless? Many philosophers have argued as to whether or not the ways in which we speak about religion are relevant or meaningful. This issue of religious language looks at the way we talk about God, debate ideas and communicate our theist or atheist ideologies. For some, religious language is meaningful and full of purpose while others see it to being incomprehensible and pointless. The verification principle a theory proposed by A.J. Ayer is a key argument, which addresses whether religious language is meaningful or not. Ayer was one of the logical positivists, a Viennese group of philosophers who were inspired by the theories of the early Wittgenstein and he sought to answer what makes a statement ‘meaningful’ as opposed to what makes it ‘true’. Ayer begins his thesis with the claim that language is only meaningful if it can be verified by a sense-observation. If you cannot demonstrate with sense-observations how a statement is true, then the statement is factually meaningless. A ‘putative proposition’ is the name Ayer gives to statements yet to be verified. A putative statement is either verifiable practically or in principle. For instance, a statement such as “that is a red car” is verifiable in practice by looking at the car. However, a statement such as “There is life in another universe” is verifiable in principle but not in practice, as we possess insufficient technology. Therefore Ayer then makes distinctions...

...INTRODUCTION The article “Marketing: philosophy of science and “epistobabble warfare” is a commentary by the author Michel Rod published as a qualitative research in an International Journal, Vol. 12 Iss. 2, pp. 120- 129. Throughout the article Rod articulated his viewpoints on the variety of philosophies involved in legitimizing the science of marketing research and sought to establish his own perspective of what he actually believes marketing research should accomplish. This was stated in his thesis statement that: “Rather than argue one particular perspective, it is this paper’s central thesis that no one philosophical perspective does or should have a monopoly on what makes a useful contribution to our understanding of marketing phenomena. “ Consequently, what Rod proposes is that rather than trying to establish an allegiance to any one particular philosophy one should be free to research, understand and articulate all the questions and results that can ‘contribute meaningful information to the study of marketing phenomena’. In other words, whilst Rod understands that a philosophy might be needed to establish foundations of ontology and epistemology to determine the methodology (POEM): - * Type of questions or problem one attempts to answer in their research * The manner in which these questions should be posed…. * The best methodological approach to shed some light on the particular question(s) being posed or the phenomenon of interest being investigated...

...15.2.2016 Reduction SAT Problem Group 1 1 Reduction 2 Reduction an important concept for understanding the relationship between problems. 3 solving one problem in terms of another Example : Suppose you have some problem A that you don’t know how to solve. If you can find a way to reduce problem A to some problem B that you do know how to solve, then that’s just as good as finding a way to solve A in the first place. 4 SORTING: Input: A sequence of integers x0, x1, x2, ..., xn−1. Output: A permutation y0, y1, y2, ..., yn−1 of the sequence such that yi ≤ yj whenever i < j. PAIRING: Input: Two sequences of integers X = (x0, x1, ..., xn−1) and Y = (y0, y1, ..., yn−1). Output: A pairing of the elements in the two sequences such that the least value in X is paired with the least value in Y, the next least value in X is paired with the next least value in Y, and so on. 5 An illustration of PAIRING. The two lists of numbers are paired up so that the least values from each list make a pair, the next smallest values from each list make a pair, and so on. 6 Solution PAIRING is to use an existing sorting program to sort each of the two sequences, and then pair off items based on their position in sorted order. PAIRING is reduced to SORTING, because SORTING is used to solve PAIRING. 7 3-step Process 1. convert an instance of PAIRING into two instances of SORTING . 2. sort the two arrays . 3. convert...

...Chapter 8 Logical Positivism I want neither that plutocracy grasping and mean, nor that democracy goody and mediocre, occupied solely in turning the other cheek, where would dwell sages without curiosity, who, shunning excess, would not die of disease, but would surely die of ennui. — Poincar´ (quoted in Runes, ToP, p. 966) e Science itself, therefore, may be regarded as a minimal problem, consisting of the completest possible presentment of facts with the least possible expenditure of thought. — Mach (Newman, WM, Vol. 3, p. 1792) 8.1 Historical Background In this chapter we will look at logical positivism, the most influential phi- Logical Analysis losophy of science in the twentieth century. In spite of the fact that logical positivism has been abandoned by most philosophers of science, its influence continues in many disciplines, including physics, linguistics and psychology. We will be especially concerned with logical positivism’s view of knowledge, which is, roughly: (1) the only real knowledge is scientific knowledge; (2) by a process of logical analysis scientific knowledge can be reduced to symbolic formulas constructed from “atomic facts.” Certainly assertion (1) is nothing new; Socrates said as much when he distinguished “scientific knowledge” 303 304 Empiricism Anglo-American Roots Continental Roots Auguste Comte: 1798–1857 CHAPTER 8.

...Logical Fallacies Fallacies are all around us. We see fallacies on the television, newspapers, and radio. People around the world experience logical fallacies on almost a daily basis. A fallacy is defined as “errors or flaws in reasoning” (Axelrod and Cooper 620).Fallacies used in advertisements are; band wagon, begging the question, confusing chronology with casualty, either-or reasoning, equivocating, failing to accept the burden of proof, false analogy, hasty generalization, overreliance on authority, oversimplifying, personal attack, red herring, slanting, slippery slope, sob story, straw man. I have gathered four advertisements that have fallacies. The fallacies are slippery slope, overreliance on authority, and hasty generalization. My first finding is an advertisement with the fallacy slippery slope. The advertiser tells people “Use this 3D White collection together and get a noticeably whiter smile in just two days”. Slippery slope is defined as pretending that one thing inevitable leads to another (Axelrod and Cooper 621). The advertisement has the celebrity Shakira smiling with beautiful white teeth. It has three Crest 3D White products a toothbrush, mouthwash, and toothpaste. Advertiser say’s “Reveal your inner rock star with a 3D White smile”. Also, it claims that “life opens up with a whiter smile”. This advertisement is pretending that life will be better if people use its products. It will also supposedly make your teeth glamorous white. The toothbrush...

...Claveria, Steven M. BSIT - II 1. What is Database Normalization? Database normalization is the process of organizing the columns (attributes) and tables (relations) of a relational database to minimize data redundancy. Normalization involves decomposing a table into less redundant (and smaller) tables without losing information; defining foreign keys in the old table referencing the primary keysof the new ones. The objective is to isolate data so that additions, deletions, and modifications of an attribute can be made in just one table and then propagated through the rest of the database using the defined foreign keys. The relational model separates the logical design from the physical design: DBMS performance is a matter of physical designer using indexes, view materialization, big buffers, etc. It is not a matter of changing the logical design. A typical example of normalization is that an entity's unique ID is stored everywhere in the system but its name is held in only one table. The name can be updated more easily in one row of one table. A typical update in such an example would be the RIM company changing its name to BlackBerry. That update would be done in one place and immediately the correct "BlackBerry" name would be displayed throughout the system. Example Querying and manipulating the data within a data structure that is not normalized, such as the following non-1NF representation of customers' credit card transactions, involves more complexity than is really...
