Assignment One: Normalising data Normalisation is a bottom-up approach to database design that begins by examining the relationships between the attributes that in turn make up the database. For this example of normalising data we are going to use data from AllRight Accounting which is a firm that stores data about their customers various policies with other companies. The forms that we are extracting the data from are standard forms used by AlRight Accounting to receive the necessary information on their customers. Here the user fills in a form with details such as Personnel Details, Policy Details, and Company Details. Aaron's Accounting Client Number: CN 34 Policy Number: PN 12 Full Name: Karen Hatfield Policy Description: Covers holder for full Dental treatment Monthly Debt: £50 Company Number: CN 100 Policy Start: 1- Sep - 99 Company Name: Dave's Dental Policy Expire: 1- Sep - 00 Source of data: Standard AllRight Accounting customer information form Before we move to First Normal Form (1NF) we show how the data looks from the outset.

No Net In Room Information. We all need it to carry on with life. Imagine living without having any idea as to what is going on in the rest of the world. Would you be able to write a report if you could not conduct research as you normally do? What would you do if you were no longer able to communicate with your close friends and family? This is what it has been like for many residents of Bowman House for the last couple of days. Somehow, our internet connection has ceased to function properly. This one event has affected me in more ways than I ever thought it possibly could. Everything from what the subject of my papers will be, to how much I communicate with my friends and family has been affected by this change. The information made available by the internet proves to be extremely helpful when writing any report. Unfortunately, this information is unavailable to me at this time. Research is not always an easy task, and for me right now, it seems to be impossible. Needless to say, the topic I wanted to write about two days ago is no longer an option. This does create some stress. All of the prewriting I did in class is now useless, as the topic I was brainstorming for I am no longer able to research easily. Communication is a very significant part of my life. It is important to me to know how my friends and family are doing. With the internet, we are all able to communicate quickly and cheaply. Right now, I have absolutely no idea how any of them are doing. Several of my friends have been having bad weeks, so I have no clue if it is getting any better for them. This puts me on...

At the beginning of 1976 there were 21,000 operational nuclear weapons in the world. Divided among six countries, nearly 95 percent of the world¡¯s nuclear weapons are in the possession of the United States and Russia. Nuclear weapons are really powerful and dangerous but a lot of countries want to possess their force. It is however debatable if having nuclear weapons is advantageous or not. Having nuclear weapons on one hand protects a country but on the other hand these weapons involve a lot of worries and expense. There are a number of disadvantages to having nuclear weapons. The basic material that makes nuclear energy possible is the fission of uranium. If people live near a nuclear weapons facility or nuclear power plant, they can suffer sick from a variety of medical conditions. Radiation from uranium poses man health risks like cancer. In the worst cases, people can even die. Furthermore, deformed babies can be born if the baby¡¯s mother lives by a nuclear facility. Professor Gary Mccuen said that the possibility of a baby being born deformed child is much higher in cities with a nuclear facility than cities with no nuclear facility. In addition, making nuclear weapons costs a lot. The materials are not cheap and the salaries for scientists are expensive. If the nuclear weapon explodes by accident it can bring terrible consequences. Even a small amount of nuclear material can cause huge damage. Scientists and researcher have known for a long time about the serious problems that nuclear power represents. Tricia Andfyszewski discussed some of these concerns in the following passage. ¡°What is the worst that could happen in a modern commercial nuclear power accident? --The worst that could happen probably would have been a release of fission products from the steam. You would have the fission products from the fuel....

NY LIFE Concept Development Assignment Team 15 Summary 1. Does NYL want to enter into the DC market? Definitely yes! DCs are the fastest growing type of pension fund; NYL can't afford to miss this opportunity! 2. What type of service(s) should NYL provide? When entering an existing market, one has to be able to compete with the existing competition; in this case the major competitors are offering total service packages. Also, according to several surveys, an important concern, for both sponsors and participants, in selecting pension plan providers is good record keeping/administrative services. These factors necessitate NYL offer a full service DC plan. Here are some specific suggestions for services NYL should offer: · In-house record keeping with possible strategic alliances with major payroll processing service provider(s) to obtain payroll/contribution information automatically with no extra effort by the employer. · Monthly, quarterly, semi-annually or annually statements (participants option). · Basic information on the first page, detailed information on subsequent pages. · Toll free phone access for daily balance and other updates (and access to they same information over the internet in the future) · Automatic reallocation for those without the inclination to personally manage fund allocation. More details are found in Attachment Two of this report. 3. Major advantages from this recommended concept. · Continued relationship building with existing customers · Reputation building to attract future customers · Complete control over the program allowing increased flexibility to meet both existing and future customer needs (both companies and individuals). These advantages will allow NYL to be a complete financial need provider for customers: insurance, assortment of retirement funds, and financial planning advice. 4. Other possibilities Contracting the record keeping services to another company requires NYL to rely on someone else being responsive to customer needs (problems will reflect poorly on NYL). Although many reputable record keeping companies exist that would probably be responsive enough, they would also charge more for that...

Class: A class is a general specification of a set of objects that defines their common structure (data), behaviour (methods) and relationships. For example Object: An object is an abstraction or simulation of physical things such as people and machines or intangible things such as events or processes that captures their characteristics and behaviour. An object has state, behaviour and identity e.g. Persistence: Persistence allows the state of the object to be saved to non-volatile storage such as a file or database and later restored even though the original creator of the object no longer exists. An example would be Encapsulation: This is a modelling and implementation technique, known as information hiding, which separates the external aspects of an object from the internal implementation details of the object e.g. Inheritance: Inheritance is a relationship between classes where one class is a parent of another. It implements "is a" relationships between objects. Inheritance takes advantage of the commonality amongst objects to reduce complexity. One class inherits part or all of the public description of another base class and instances inherit all the properties and methods of the classes which they contain e.g. Polymorphism: A concept in type theory according to which a name (such as a variable declaration) may denote objects of many different classes that are related by some common super-class. Thus any object denoted by this name is able to respond to some common set of operations in different ways. For example Object Oriented Life Cycle: The OO Life Cycle of a software development project can have several incremental steps. Each of these increments consists of Iteration Cycles whereby specific phases of development are carried out. Each cycle consists of an Analysis, Design, Implementation and Testing phase where certain deliverables are produced. The iterations are repetitive by nature as the project evolves over time. Analysis: The analyst looks at the existing real world scenario...

Object-Oriented Programming the desire for an easy transition from existing languages ABSTRACT Now it is clear that Object-Oriented Software Development is here to stay and is the preferred way to develop software. To be successful in the world of object-oriented programming (OOP) one has to unlearn quite a few of the habits acquired from the years of procedure-oriented programming and learn some new ways of looking at the problems. Object-oriented technology is the wave of today. Thus it is my intent in this paper to give a brief overview of object-oriented programming, discuss the concepts of abstraction, encapsulation and information hiding (as applied to OOP). This paper will also show the importance of OOP in software re-use and also try to distinguish between object-oriented languages and object-based languages. Keywords Encapsulation, object-oriented programming (OOP), abstraction, objects, classes. INTRODUCTON Object-Oriented Programming requires a thorough understanding of some fundamental paradigms, or concepts. Understanding these paradigms is essential to building a strong foundation in the OO software world. Any language that supports OOP must support these fundamental paradigms. In other words, learning a set of powerful paradigms that are supported by many languages like Smalltalk, C++, Java, etc. Learning the syntax of a language that supports OPP is not the same as learning the concepts of OOP. One might be good in C++ or Java without any knowledge whatsoever of the basic OOP paradigms. On the other hand, anyone who understands the fundamental concepts of OOP will be able to use those concepts effectively with any languages that support OOP and they should also know when to use a particular concept. So learning OOP concepts is just one milestone, but that is not the ultimate destination of any programmer/designer. One should be able to apply these concepts to problems in one's domain or area of expertise. Thus this paper tries to briefly...

The twentieth century has witnessed a great number of fascinating and amazing changes among which, I believe, the internet technology is the one that should be remembered because it has created not only a rapid and affordable form of communication but also a valuable method for allowing better access to information. Generally speaking, the internet has improved communication in the twentieth century tremendously. The wide use of email is a good case in point, which is an excellent and efficient way to keep friends, coworkers or family members in touch. Before the existence of the internet and email, most people have to mail their letters through post office, which is slow and costly, especially when the cities are far apart in distance. With email, however, one can received his or her letters almost as soon as they are sent out. I myself am a heavy user of email and I really appreciate the convenience it brings to me. Because it makes it possible that I write to my parents and friends at homeland everyday even though I am now living far away from my native country. Furthermore, the internet is responsible for quicker and easier access to information. Firstly, one can almost gain all kinds of information online today, such as weather forecast, movie reviews or cooking recipes and so on. Secondly, we don't have to wait for television news or read newspaper once a day for international news because we can read latest news and top stories on internet whenever we want to. Last but not least, for our students, we can easily get the information of almost every school all around the world by visiting the website of that school. The twentieth century is the information era as the result of the increasing important role played by information in current...

Creative processes that solve disputes without turning to litigation have existed for many years. Candidly called "Alternative Dispute Resolution", the three general methods that have emerged and developed in the past two decades are negotiations, mediation and arbitration. More recently a fourth approach is being put to the test, which combines one or all of these forms of ADR with the technology revolution, fondly called "Online Dispute Resolution". Although ADR and ODR are superficially sound ideas, the perceived worth of ADR methods have yet to triumph over traditional litigation. Why is this so? Moreover, moving the ADR process online brings with it not only the same disadvantages, but new ones as well. This paper will address some of the fundamental concerns and problems that may come to undermine the potential of "Online Dispute Resolution" (ODR) however, it will also suggest some very bona fide niches where ODR may excel if properly marketed. By providing a properly marketed ODR program within the proper niche, an argument citing the lack of "critical mass" can be overcome and ODR's viability may be concretely established. traditional adr methods Before we investigate the intermingling of ADR and technology, it may be prudent to review some rudimentary principles associated with traditional ADR processes. Negotiation Negotiation is by far the common form of dispute resolution. Negotiations can be entered into at almost any stage of almost any given conflict. And is loosely defined as a communication process that people use to plan transactions and resolve conflict. Through the process of negotiation the individual parties gradually may be able to come together into coordination and collusion and, in the end, to some agreement on the issues between them. Mediation Mediation utilizes the assistance of a neutral party for the exchange of information. Richard Hill, who uses the simple example of an orange, presents a favorite illustration....

Although for half a year the Internet had been undergoing bise and cold rain, which tumbling itself down from the altar, no one would deny that the Internet is still the trend of the future. On this condition, the traditional industry contact intimately with network one after another, so does the educational industry. In economics point of view, demand is the only drive of development. Along with Chinese opening up policy, the conception, which education determines future, goes deeply into people¡¯s heart, with a result of more and more educational investment. With the development of society, the competition is increasing fiercely. Many parents will never scant money when investing in next generation¡¯s education so that their children can have a better future. In this way the education cake is really so big that a very tiny part of it can fill website¡¯s stomach. That is no wonder why the sharp-nosed trader scramble for it. A wonderful expectation does not guarantee a perfect reality. The way to our dream is usually filled with thorns, therefore educational website must stride forward three thresholds. First, diploma issued by universities is far better than that given by online education institute. So you will meet with many trouble without authoritative diploma. Secondly, Traditional educational system has been developed perfectly till now. Then if educational website do not make great efforts to curricula setting, teaching quality and schoolwork management, it will be difficult for them to get a cup of thick soup from the delicious education meal. Also the technology of whole network distinguishes greatly. There is no doubt that bandwidth of domestic network is not as adequate as to transmit multimedia courseware, never to say the real long distance education. Surely online education inaugurates a span-new study method, but it still has a long way to go....

EFFECTIVENESS OF ONLINE INSTRUCTIONAL DELIVERY VERSUS TRADITIONAL CLASSROOM DELIVERY IN COLLEGE COURSES In the past years education has witnessed a boom in regards to the acceleration of technology use in the classroom. Along with the rise of internet use in traditional classroom instruction, the rise of online classroom instruction has become a necessity when trying to keep up with the demands of student learning in the technology age. Education today finds itself faced with the challenge of maintaining emphasis on student learning it terms of knowledge, competencies and skills in their curriculum all while competing for student enrollment in the on line instructional classroom model. Educators need to determine if the levels of learning in an online classroom are as effective as in the traditional classroom setting. In the study by Schulman and Sims ( 1999) they assess as more and more online courses and programs proliferate, the question of quality and comparability of such instruction with traditional methods naturally arise. There are many studies on the impact of technology on student learning that use survey and interviews to gather qualitative data on the self reported attitudes from student and teachers to make value judgment on the technological advancements in on line instruction. As T.H.E. Journal, unknown author, reported to date the most methodologically sound investigation to evaluate effectiveness of online instruction was conducted by Gerald Schutte at Cal State. In his study Schutte randomly divided his statistics class into two groups. The controlled class attending class regularly, listened to lecture, handed in homework assignments and took examinations. The experimental group took an online version and met with professor by chat, completed assignments by internet and email, and only attended class to take the mid term and final exams. Dr. Schuttes result found that the wired students outscored their traditional student counter parts...

Online Music Distribution in a Post-Napster World Case Study Background Information • Service has been shut down since July 2001. • June 3, 2002, Napster Filed for bankruptcy. • October 29th, 2003, Napster will re-open with its new pay service. • Conflicting rights: 1. The rights of artists and record labels to receive payment for their labors 2. The rights of consumers to share their favorite songs with fellow internet users 3. The rights of copyright holders to protect their intellectual property 4. The rights of entrepreneurs to push the limits of technology • By 2002, a study found that 13 million of U.S internet users were downloading music they didn't previously own. • The Napster service reached its peak usage in February 2001, when an estimated 80 million people were members of the Napster community, and over 1.5 million people were using the service at any given time. • Recording Industry Association of America (RIAA), filed suit representing the interests of the record labels regarding fair compensation. • The band Metallica followed with an additional lawsuit against Napster, claiming the file swapping was piracy. • Napster defended their interests by pointing to the Audio Home Recording Act (AHRA), which allowed consumers to record and share music with their peers for noncommercial purposes. • The average CD price for consumers was $16.98. Key Issues: • A typical major-label release needed to sell about 500,000 copies in order to break even. • In 2001, RIAA stated there was a 4.1% decline in music sales from the previous year, which is the largest in a decade. • Since the distribution of music via the Internet was so explosive, major record companies aggressively pursued online music distribution strategies. • These strategies did not do very well with mainstream file swapping public Music could not be swapped or burned on to CDs If one stopped paying for the service all music would expire and could...

Object oriented programming leads to a more layered approach to programming than is available with structured programming. A procedural based application typically will start at line 1 and will continue in a linear manner until line xxxx is reached. Here the application will terminate or, if this is not desirable, the entire application must be nested inside a gigantic loop to restart the process again. Using OO, and more importantly OO design methods, an application can be split into logical elements. For instance, a sales order processing application may be defined as the interaction of a customer, the parts and the accumulation of these to form an order. As there is specific information needed for a customer (name, address, account no.) this would logically be suitable as an object in its own right. The same could be said for parts (part no., description, price) and this too would be worthy as a separate object. An order is also a credible object but is merely an accumulation of customer and part objects with some extra information to determine order no., despatch method etc. Having defined these 'business' objects it then needs to be considered how these can be pieced together to form the process of creating a sales order. There are two elements to this, firstly the users view or screens that are required to operate the process and secondly the logic behind that process. What I have tried to briefly describe is a methodology called MVC (Model, View, Controller). The model being the objects, the view being the screens displayed to the user and the controller is the application logic that handles the interaction between the users input (view) and the objects themselves. The benefits of contructing applications in this manner are great, for example, if an additional piece of information is needed to...

Main developments in operating systems An operating system (sometimes abbreviated as "OS") is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI). A GUI (usually pronounced GOO-ee) is a graphical (rather than purely textual) user interface to a computer. As you read this, you are looking at the GUI or graphical user interface of your particular Web browser. The term came into existence because the first interactive user interfaces to computers were not graphical; they were text-and-keyboard oriented and usually consisted of commands you had to remember and computer responses that were infamously brief. The command interface of the DOS operating system (which you can still get to from your Windows operating system) is an example of the typical user-computer interface before GUIs arrived. An intermediate step in user interfaces between the command line interface and the GUI was the non-graphical menu-based interface, which let you interact by using a mouse rather than by having to type in keyboard commands. MS-DOS MS-DOS (Microsoft Disk Operating System) was the Microsoft-marketed version of the first widely installed operating system in personal computers. Most users of either DOS system simply referred to their system as Disk Operating System. Like PC-DOS, MS-DOS was (and still is) a non-graphical line-oriented command-driven operating system, with a relatively simple interface but not overly "friendly" user interface. Its prompt to enter a command looks like this: C:> The first Microsoft Windows operating system was really an...

Organizational Analysis Pacific Bell Pacific Bell as it is now, is a subsidiary of Southwestern Bell Corporation (SBC). The history of the company dates back almost 125 years to the actual invention of the first telephone by Alexander Graham Bell on March 10, 1876. Bell Telephone Company was the first formal phone company and it developed rapidly throughout the United States. In 1878 they re-organized and started the beginnings of what we now know as regional phone companies by creating New England Telephone. Then within 2 years the company incorporated as National Bell Telephone only to change its name to American Bell the following year 1880. It would be only five years later that the first long distance company was started. (Farley) AT & T American Telephone & Telegraph was created in 1885. American Bell was able to buy out the competition Western Electric Telephone (a company owned by Western Union) and eliminate its only real competition to capitalize and strengthen their market place. Only AT&T provided long distance to American Telephone and only American Telephone users were able to connect to the AT&T network. The system was complete and a true monopoly was created and it wouldn't be broken for over 100 years. (Brooks) Over the course of the next twenty the years the company would criss-cross the country and secure a firm place in the industry. The industry was ever changing but change was at relatively slow pace compared to technology today. The real breakthrough happened in the late 1940's with the unveiling of the Bell Laboratories transistor. No one knew how much that would change the face of technology and the world, as they knew it. (Farley) Bell American (Bell) had already begun to branch out and by now they had a local phone company in every region of the...

in the 1940's • Bored teenagers began fabricating their own cars from the vintage frames of 1920's and 1930's Fords and Chevys. • They began racing these cars along the dry lakes of Southern California, testing themselves against each other in timing trials. • The first proven formula cars were vintage American gangster mobiles; Fords and Chevys, especially the '32 Fords with the first V-8 engine. • Street racing began to take over whole city blocks, but the cops let it go; it wasn't legal but it was considered harmless, even acceptable. Street Racing in the 1950's • 50's Greasers formed the first street racing teams who collaborated on one high performance car, one with an engine that was bored and stroked with headers and Mallory ignitions. • The team identity was a necessary step in improving the overall anatomy of a hotrod. • Stoplights across America had become unofficial street racing launch pads, and the police were making arrest. Street Racing in the 1960's • The commercialization of street racing lead to the creation of "Drag Racing", an attempt to give the pastime a sense of solidarity as a sport, and to make street racing less dangerous by pulling it off the streets. • Visionaries like George Harris and his "Batmobile" camouflaged street racing behind a veneer of Hollywood camp. • The popularization of the street racing culture brought forth the poet of decal, Ed "Big Daddy" Roth. • The desire to street race outside the establishment continued to gain support and the "taming" of street racing had had the reverse effect of expanding the boundaries of the racing participants. • A hot Oldsmobile or Buick replaced a Ford or a Chevy as the street racing car of choice.

There has been a vision about an idea called the "paperless office" since the 1980s on how it would impact the business world. The main idea of the paperless office is to conduct business transactions without sorting memos, reports, or anything that is printed on paper. Many considered the potential advantages of having personal computers in every house in the future. People are fascinated by the power of computers and by the new opportunities they provide. People started to think of how computers will affect the future. A paperless society was the most obvious vision. First, people were tired of papers overloading their offices, and secondly they became more conscious about the environment aspects. The future looked so bright back then. No more paper clutter plus no more trees being cut just for the paper. Everything, including books, will be stored on disks and other electronic media. There are Web-based business forms that are completed and stored entirely online. More importantly, the data contained in the forms, including signatures, can be processed in databases to create detailed online financial reports. E-mail is without a doubt, the Internet's most popular application. In my opinion, it is among the first services users get hooked to when they log on to the Internet. For the past few years, people have started E-mailing everything from letters to greeting cards to making the world a smaller place. As the use of E-mail started, should not the amount of mail being sent through the postal system decline? The relationship between the two is more complicated than many people realize. For example, America Online (AOL), a provider of Internet access to at least 28 million subscribers around the world, facilitates billions of e-mail exchanges. Yet, the company is also the fastest-growing user of direct mail in the United...

THE IMPACT OF COMPUTERS Computer technology not only has solved problems but also has created some, including a certain amount of culture shock as individuals attempt to deal with the new technology. A major role of computer science has been to alleviate such problems, mainly by making computer systems cheaper, faster, more reliable, easier to use. Computers are forever present in the workplace. Word processors-computer software packages that simplify the creational and modification of documents-have largely replaced the typewriter. Electronic mail has made it easy to send messages worldwide via computer communication networks. Office automation has become the term for linking workstations, printers, database system, and other tools by means of a local-area network. An eventual goal of office automation has been termed the "paperless office." Although such changes ultimately make office work much more efficient, they have not been without cost in terms of purchasing and frequently upgrading the necessary hardware and software and of training workers to use the new technology. Computer integrated manufacturing is a relatively new technology arising from the application of many computer science sub disciplines to support the manufacturing enterprise. The technology of CIM emphasizes that all aspects of manufacturing should be not only computerized as much as possible but also linked together via a computer communication network into an integrated whole. In short, CIM has the potential to enable manufacturers to build cheaper, higher-quality products and thus improve their competitiveness. Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in...

H.N.C MULTI-USER OPERATING SYSTEMS REPORT CHARLES .S. SPENCE 1. Terms of Reference: 1.1 David King, Lecture IT department Coatbridge College, has asked for the following report to be compiled on Multi-User operating System. The report should be submitted for the week of 6.4.2003 in connection with all the information gained during this period, and to make recommendations as appropriate. 2. PROCEDURE: The information contained within this report was compiled in the following manner. ľ Discussion David King, Lecturer IT department Coatbridge College ľ Information taken from course notes & lectures. ľ Internet resources. 3. FINDINGS: 3.1 Main features of multi user operating system. 3.1.1 Resource Sharing What resourse sharing means is that the operating system must manage all the resources must be managed in such a way that all processes run some of the time and that the get the resources needed to enable them to complete their task. 3.1.2 Multi-user operating systems are used on large computers. A mainframe computer system has one very powerful processing unit. And the random access memory, which write to and read from storage devices such as disk drives, input and output devices such as printers and disk drives many users, will all share this processing unit. 3.1.3 The operating system is the most important item of software on any computer. This is automatically loaded when the system is switched on and runs continually whilst the system is on. This software continually communicates with hardware and software programs such as word processing continually ensuring that operations are running smoothly. 3.2 Multi-tasking Multi-tasking systems support foreground and background processes, tasks. A foreground task is one that the user interacts directly with using the keyboard and screen. 3.2.1 In a computer system that supports more than one process at once, some mechanism must be used to switch from one task to another. There are two main methods used to perform this switching. Co-operative switching means that...
