All the DBMS have two basic sets of Languages - Data Definition Language (DDL) that have the set of commands needed to define the format of the data that is being stored and Data Manipulation Language (DML) which tells the set of commands that modify, process data to make user definable output. The DML statements can as well be written in an application program.
