SQL (Structured Query Language) is a standard language for storing, manipulating, and retrieving data in relational databases.

SQL was initially developed at IBM in the 1970s, It became a standard of the American National Standards Institute (ANSI) in 1986.

SQL is the standard database language for Relational Database Management Systems (RDBMS) like Oracle, MySQL, MS SQL Server, MS Access, IBM DB2, Informix, and PostgreSQL, etc.

Although most database management systems use SQL, most of them also have their own additional proprietary extensions that are used on their system only. ex: Pl/SQL in Oracle, Transact-SQL in MS SQL Server.

Subsets of SQL are Data Definition Language (DDL), Data Manipulation Language (DML), and Data Control Language (DCL).

SQL Skills are required for Database Developers, Database Administrators, and Database Testers (Manual Testers and Automated Testers).
