  • 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 ...

  • 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 ...

  • 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 ...

    ... that the questionnaire was difficult to fill out since they recruit for different positions in various departments: Computer skill expectations vary depending on the department one joins. One recruiter even concluded that computer-skill requirement varies by engineering discipline. Many employers agreed that computer literacy is important to all, and that if a student graduates without any [skills], he/she will have a distinct disadvantage in the workforce. Lacking these skills would not exclude most college graduates from the job market, however, the more skills they exhibit, the more attractive they would be to potential employers. Communication Skills though this study looked only at ...
