SQL stands for structured query language. It is a language that can be used for retrieval and management of data stored in relational database. It is a non-procedural language as it specifies what is to be retrieved rather than how to retrieve it. It can be used for defining the structure of data, modifying data in the database and specifying the security constraints.
The two major categories of SQL commands are Data Definition Language (DDL) and Data Manipulation Language (DML). DDL provides commands that can be used to create, modify and delete database objects. DML provides commands that can be used to access and manipulate the data, that is, to retrieve, insert, delete and update data in a database.
