Managing Information Systems In Organizations Essay -- Database Manage

Managing Information Systems In OrganizationsINTRODUCTIONIn late years, there has been an abundance of new technologies in the reading systems field. These new technologies cast off altered the very development process itself. Information systems have kaput(p) 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, craft has taken on an entirely different function, and the need for individual information systems has grown immensely. This demand for information technology is in all areas of dividing line corporations, law, medicine, science and even small business. In addition, the worldwide web and the earnings have added an additional factor of communications. Most information systems in expend today require at the very least, a measure of net income capabilit y.In order to down the stairsstand the changes in these development processes, the history of databases should be analyzed.BACKGROUNDDatabase steering Systems actually began in the 1950s, with what is known as the stolon contemporaries, also known as file systems on tape. The major childbed of any computer in those days was to process data under the control of a course. This primarily meant calculating, counting and simple tasks. Second generation databases, file systems on disk, allowed use of computers in dialogue mode as well as batch mode. The development of magnetic disks allowed for more innovative file systems, making multiple access possible. These first two generations of database management system were characterized by the availability of file systems only strictly speaking these were the forerunners of database systems, the foundations. An pregnant component of these database systems were the static association of certain data sets (files) with individual programs that would condense on these. There were high redundancy problems between files inconsistencies when one program made changes that are not made in all programs inflexibility against changes in applications low productivity by programmers since program maintenance was big-ticket(prenominal) and the problem of adopting and maintaining standards for coding and data formats. The third generation, pre-relational databases, started in the 1960s a... ... quick development in this area, not only in technology merely also in functionality. Information Systems will rapidly emerge into a wealth of applications until it eventually becomes an extension of the person (maybe in a existent sense some day). That, I believe, is the future.Works CitedCattell, R.G.G., Object Data Management Object-oriented and Extended Relational Database Systems Reading, MA Addison-Wesley Publishing Company, 1991.Gagnon, Gabrielle, Data Warehousing An Overview PC Magazine, March 9, 1999.Hammond, Mark, DRDA Sta ndard Could Finally Get Rival Databases Talking, PC Week, December 7, 1998.Mayor, Tracy, Look Ma, No Hands PC Week, July 1, 1996.Coskun, Samli A., Information-Driven Marketing Decisions cultivation of Strategic Information Systems Quorum Books, 1996.Schindler, Esther, The computing device Speech Book Academic Press, Inc., 1996.Sichel, Daniel E., The Computer Revolution - An Economic Perspective The Brookings Institution, 1997.Vossen, Gottfried, Data Models, Database languages and Database Management Systems Wokingham, 1991.Watterson, Karen, Blueprint For A Database Data Based Advisor, June, 1990.
