SQL (Structured Query Language) is the most common standardized language used to access databases.
SQL was originally developed by IBM in the 1970′s for their DB2 RDBMS.
SQL version 3 is officially defined by the American National Standards Instititute (ANSI) in the ANSI SQL:1999 standard.
Most existing DBMS’s currently conform to the earlier ANSI SQL92 standard.
SQL is a nonprocedural language. Oracle produces a procedural version of SQL which it calls PL/SQL.
SQL is supported by every major database system in use today, including MySQL, PostgreSQL, Berkeley DB, Oracle, DB2, Sybase, Informix, and Microsoft SQL.
SQL is often pronounced “sequel”.
