Structured Query Language (SQL) is a widely-used programming language for working with relational databases. SQL is generally pronounced as the three letters in the name, e.g. ess-cue-ell, or in some people's usage, as the word sequel.
This Wikibook provides a short description of SQL, its origins, basic concepts and components, and a lot of examples. The book follows the specifications of the SQL:2011 standard, which is developed by a common committee of ISO and IEC. Their publications are not freely available. But you may want to refer to a working draft of SQL:2008, which you can download from Whitemarsh Information Systems Corporation.
