SQL stands for Structured Query Language. The SQL language as a query language, it can do much more than just query a database. It can define the structure of the data, modify data in the database, and specify security constraints.

A database system provides a data definition language to specify the database schema and a data manipulation language to express database queries and updates. In practice, the data definition and data manipulation languages are not two separate languages; instead they simply form parts of a single database language, such as the widely used SQL language.
