| Short
for Structured Query Language, SQL is a language originally known
as SEQUEL (Structured English QUEry Language) that was developed by
Dr. E.F. Codd at the IBM research center in
1974. Later shortened to SQL
but still pronounced as sequel, SQL has become the de
facto standard database language.
The first commercial version of SQL
was introduced in 1979 by Oracle.
Today, there are three standards of SQL, SQL89 (SQL1), SQL92 (SQL2),
and SQL99 (SQL3), and numerous flavors of SQL available.
