A database management system ( DBMS) is a software package with computer programs that controls the creation , maintenance, and use of a database.

Data can be organized in two types:

  • Flat File : Data is stored in a single table. Usually suitable for less amount of data.
  • Relational : Data is stored in multiple tables and the tables are linked using a common field. Its used for medium to large amount of data.
