  • College Accepatance About Programming - 278 words
    College Accepatance about Programming My past projects centered around analyzing, formulating and delivering solutions in every stage of providing Microsoft-format software for major Fortune500 companies. I have also designed a database system (implemented in SQL Server) and developed front end applications in Visual C++ and Visual Basic that used ODBC and DAO to access the server. This work piqued my interest in doing research in the field of database systems, and I started to think more analytically about the limitations of relational databases. I became interested in object-oriented databases, particularly their flexibility and their ability to meet the requirements of more complex struct ...

  • Databases - 698 words
    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 ...

  • I Statement Background - 1,358 words
    I. STATEMENT & BACKGROUND The college of Business (COB) server is now being used to support deliver to the Computer Information System (CIS) department. The CIS professors would be using the server for various operations. Assignments, e-mail, and other types of information would be easier for the students to access. Network users are able to share files, printers and other resources; send electronic messages and run programs on other computers. However, certain important issues need to be addressed and concentrated on. In order to begin the process of setting up the COB server, the total numbers of users (faculty and students) must be determined. Some other significant factors to be approach ...

  • Managing Information Systems In Organisations - 1,280 words
    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 ...

By 1956, 76 of IBMs large computer mainframes were in use, compared with only 46 UNIVAC's. In the 1960s efforts to design and develop fastest possible computers with the greatest capacity reached a turning point with the completion of the LARC machine for Livermore Radiation Laboratories by the Sperry-Rand Corporation, and the Stretch computer by IBM. The LARC had a core memory of 98,000 words and multiplied in 10 microseconds. Stretch was provided with several ranks of memory having slower access for the ranks of greater capacity, the f ...

    Privacy And Information Technology Geoffrey Graves MG3700 Mid Term Exam 4/24/2000 Part I 1.) In order to produce an upwards swing in revenue, Toy World must track its customers buying trends with more accuracy and more detail. The Point of Sale system that they are currently working from can be improved and made to reduce after-market inventory. Trend data can be used for a wide variety of purposes. One of the first problems is the store design and layout of items. Sale items and hot merchandise must be as strategically positioned as possible to allow a prospective customer to locate and remove the item from the shelf quickly and painlessly. By analyzing customer data, the new system must be ...

  • The Use Of Data Warehouse In Decision Making Process - 1,625 words
    The Use Of Data Warehouse In Decision Making Process INTRODUCTION It is obvious that there is no organization running without data. The data can be viewed as tangible assets of an organization just as any physical asset. So, they need to be stored and made available to those who need them when they need them. However, the data by themselves are useless. So, they must be put together to produce useful information. In turn, information becomes the basis for relational decision making. To facilitate the decision-making process, a new development of database systems was developed called "data warehouse". The data warehouse can be generally described as a decision-support tool that collects its d ...

  • Y2k - 1,666 words
    Y2k This year, most of the world is preparing to celebrate the year 2000 and the coming of a new millennium. However, many businesses, manufacturers, banks and hospitals are quietly hoping for an uneventful new years transition. At midnight on December 31, many businesses will be anticipating what effects the millennium rollover will have on computer software and other equipment that contain a time sensitive chip called an embedded chip. Early computer programmers, in an effort to conserve limited memory space, programmed computers to read the year in only two digits. So computers read 15 as 1915, and 02 as 1902, and so on. Thus, when the year 2000 arrives, many computer programs might go fr ...
