It is a state of the art information system process and retrieve information ever faster, they are more robust in terms of the volume of data that they can process and in terms of reliability; and their performance is more cost-effective. The central component of information system, the database may be distributed over a number of processor in different geographic locations, yet queries can processed simultaneously against the composite database. Managing a database is inherently a complicated task. Fortunately, software packages called database management system can do the work.
