Managing Information Systems In Organizations Essay -- Database Manage

Managing entropy Systems In OrganizationsINTRODUCTIONIn recent years, there has been an abundance of sensitive technologies in the instruction systems field. These new technologies have altered the very ripening process itself. nurture 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 simulated 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. This demand for information technology is in all areas of business corporations, law, medicine, science and even meek business. In addition, the worldwide web and the Internet have added an additional compute of communications. Most information systems in recitation today require at the very least, a measure of Internet capability.In order to attend the changes in these development processes, the history of databases should be analyzed.BACKGROUNDDatabase Management Systems real began in the 1950s, with what is known as the first generation, also known as stick systems on tape. The major task of any computer in those days was to process data under the control of a program. This in the beginning meant calculating, counting and simple tasks. Second generation databases, file systems on disk, allowed use of computers in dialogue mode as well as hole mode. The development of magnetic disks allowed for more sophisticated file systems, making seven-fold access possible. These first two generations of DBMS were characterized by the availability of file systems only strictly speaking these were the forerunners of database systems, the foundations. An important component of these database systems were the static affiliation of certain data sets (files) with individual programs that would concentrate on these. There were lofty redundancy problems between files inconsistencies when one program made changes that are non made in all programs inflexibility against changes in applications low productivity by programmers since program maintenance was expensive and the problem of adopting and maintaining standards for coding and data formats. The third generation, pre-relational databases, started in the 1960s a... ... rapid development in this area, not only in technology but also in functionality. Information Systems will rapidly emerge into a wealth of applications until it eventually becomes an quotation of the person (maybe in a literal 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 Standard Could at last Get Rival Databases Talking, PC W eek, December 7, 1998.Mayor, Tracy, Look Ma, No Hands PC Week, July 1, 1996.Coskun, Samli A., Information-Driven Marketing Decisions Development 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 military position 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.
