  • About Database

    A database is a collection of data stored and maintained for one or more uses. Most modern databases are managed by a Database Management System (DBMS), a set of computer programs that controls the creation, maintenance, and the use of the database with computer as a platform or of an organization and its end users. It allows organizations to place control of organization-wide database development in the hands of database administrators (DBAs) and other specialists.

    The proper integration of databases can dramatically increase the functionality of all types of applications, whether or not Web-enabled.
