A collection of data is referred to as database and a database (management) system is basically a computer based record keeping system. It maintains any information that may be necessary to the decision-making processes involved in the management of the organization. The intention of a database is that the same collection of data should serve as many applications as possible.

It may be possible to search the database to obtain answers to queries or information for planning purpose.
