A database management system (DBMS) consists of a collection of databases and a set of programs that enable users to create and maintain the data in the databases. The DBMS must provide an appropriate database language for each category of users such as database administrators (DBAs), database programmers, and end users. In general, a database management system provides two different types of languages: a data definition language (DDL) to specify database schema and a data manipulation language (DML) to retrieve, insert, delete, and modify data.
