ABSTRACT
The Structured Query Language (SQL) is a language for working with information that has been stored in a database.
SQL has three parts: the Data Manipulation Language (DML) concerns adding information to a database, modifying the information, and extracting information from a database; the Data Definition Language (DDL) is concerned with the structure of a database (creating tables); and the Data Control Language (DCL) is concerned with administration of a database (deciding who gets what sort of access to which parts of the database).
