(Structured Query Language) Typically pronounced "see-quill" rather than the acronym, SQL is a language used to interrogate and process data in a relational database. Originally developed by IBM for its mainframes, SQL commands can be used to interactively work with a database or can be embedded within a script or programming language to interface to a database. Programming extensions to SQL have turned it into a full-blown database programming language, and all major database management systems (DBMSs) support it.

ANSI standardized SQL, but most DBMSs have some proprietary enhancement, which if used, makes SQL non-standard. Moving an application from one SQL database to another sometimes requires tweaking, the age old problem in this business! See MySQL, SQLite, MDX, CLI, ODBC, IDAPI and SQL injection.
