Computer Based Systems The system Development Cycle What is it? The system development cycle is a method used to create a system where none has existed before and/or modify an existing system. It is sometimes simply called System Development. It involves a number of stages representing a standard strategy for taking a problem from start to finish. Two approaches: 1. Conservative-working systematically through the steps. 2. Radical-Cycling through the cycle several times until the final result is achieved. The Steps The above diagram shows that the system development cycle is represented by 5 broad stages: -Requirements Definition. -Analysis. -Design. -Implementation. -Operation and Evaluatio ...

- Data Mining In A Nut Shell - 1,744 words
Data Mining In A Nut Shell In today's business world, information about the customer is a necessity for a businesses trying to maximize its profits. A new, and important, tool in gaining this knowledge is Data Mining. Data Mining is a set of automated procedures used to find previously unknown patterns and relationships in data. These patterns and relationships, once extracted, can be used to make valid predictions about the behavior of the customer. Data Mining is generally used for four main tasks: (1) to improve the process of making new customers and retaining customers; (2) to reduce fraud; (3) to identify internal wastefulness and deal with that wastefulness in operations, and (4) to c ...

Databases The Many Faces of Databases Large databases can contain hundreds of interrelated files. Fortunately a database management system can shield users from the complex inner workings of the system, providing them with only the information and commands they need to get their jobs done. In fact, a well-designed database puts on different faces for different classes of users. Downsizing and Decentralizing The earliest file management programs could only do batch processing, which required users to accumulate transactions and feed them into computers in large batches. These batch systems weren't able to provide the kind of immediate feedback we expect today. Today disk drives, inexpensive m ...

Direct-Mail Advertising Direct-Mail Advertising Advertising may be described as the science of arresting the human intelligence long enough to get money from it. Stephen Leacock Philosopher extraordinaire Really good direct mail works like picking your prospect up by the ankles and shaking him until all the money falls out of his pockets.

Direct-Mail Advertising As consumers, we are often bombarded by different types of advertisements each day. Whether its by television, newspaper, or billboards, advertising has reached us one way or another. Yet, a majority of the ads that we encounter are often meaningless and uninteresting, because of the fact that these ads are meant to reach a certain target audience. This perception seems to change, however, when we look inside our mailboxes, pick-up our telephone, and even check our e-mail. We often ponder how marketers know that we have a pet snake, own a certain kind of computer, or even wear 70s clothing. That is because everytime we purchase products such as: electronics, computer ...

Managing Information Systems In Organisations INFORMATION SYSTEMS DEVELOPMENT PROCESS INTRODUCTION In recent years, there has been an abundance of new technologies in the information systems field. These new technologies have altered the very development process itself. Information systems have gone from being a series of one level databases to three dimensional reality, virtual reality, and multimedia systems. In the early days of information systems, the demands were for data, with no real function of artificial intelligence. However, as the 21st century approaches, business has taken on an entirely different function, and the need for individual information systems has grown immensely. Th ...

... ee, allowing the user to use a computer without a keyboard. Perhaps, there will be a time when a keyboard and a mouse become obsolete. The major technical challenge in speech recognition is to provide a high degree of accuracy while supporting use of continuous speech. Improving speaker independence and vocabulary size is of equal importance. According to Esther Schindler, "Speech will become more and more a part of computing and as it does so, the lines between "getting work done" and conscious computing will blur. The speed at which this change will occur will be based on the rate at which the technology becomes cheaper, faster, smaller, more efficient, and solves peoples problems. As ...

- Objectoriented Database Management Systems - 1,624 words
Object-Oriented Database Management Systems The construction of Object-Oriented Database Management Systems started in the middle 80s, at a prototype building level, and at the beginning of the 90s the first commercial systems appeared. The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors, that is the relational database management systems. They were intended to be used by applications that have to handle big and complex data such as Computer Aided Engineering, Computer Aided Design, and Office Information Systems. The area of the OODBMSs is characterized by three things. First, it lacks a common data model. There is no ...

... ld be extensible i.e. the user should be able to define his/her own types and treat them in the same way he/she treats the predefined ones. In other words, user types and system types should have the same status although perhaps they are differently supported by the system itself. Persistence is one of the most basic features of a DBMS (at least the most evident one) and hence of an OODBMS. It is the ability of the programmer to have his/her own data survive the execution of a process so that he/she can eventually reuse it in another process. For an object-oriented system, there is an additional requirement which stems from the extensibility requirement, that any object must be able to b ...

- Relational Databases - 1,092 words
Relational Databases Relational databases have long been associated with big enterprises, but lately they've been finding their way to an audience of different users. Now, most large-scale web sites use databases for at least some portion of their content. User registration information, inventory records, and event calendars are all managed through a database. Databases are applications running on the server that provides quick and efficient access to large amounts of organized data. In addition to storing information, databases can establish a relationship among various pieces of data, provide powerful sorting, searching, and merging capabilities. Databases can also help manage access to da ...

- Tele Education - 3,949 words
Tele Education 1.0 INTRODUCTION 1.1 Background of Tele-education Tele-education has a long history beginning with systems like that for teaching children in Australian Outback, the British Open University and other such organizations. These built on the idea of correspondence courses where course materials are sent periodically by post and augmented the experience with broadcasts either on radio or on TV. The problem of student isolation was addressed partially through techniques such as telephone access or two-way radio links with teachers. At the end of 1980s, the vest majority of distance education throughout the worlds was still primarily print-based. Technologies used for distance educa ...
