The data is managed by systems software called database management systems (DBMS).The data stored in a database is independent of the application programs using it and of the types of secondary storage devices on which it is stored.Database - is an integrated collection of logically related records or files.
It also provides a language for manipulating the data, called the data manipulation language (DML), which makes it possible to access records, change values of attributes, and delete or insert records.
Direct file organization provides the fastest direct access to records.
When using direct access methods, records do not have to be arranged in any particular sequence on storage media.
