Abbreviation of structured query language, and pronounced
either see-kwell or as separate letters. SQL is a
standardized query language for requesting information from
a database. The original version called SEQUEL (structured
English query language) was designed by an IBM research
center in 1974 and 1975. SQL was first introduced as a
commercial database system in 1979 by Oracle Corporation.
Historically, SQL has been the favorite query language for
database management systems running on minicomputers and
mainframes. Increasingly, however, SQL is being supported
by PC database systems because it supports distributed
databases (databases that are spread out over several
computer systems). This enables several users on a local-
area network to access the same database simultaneously.
Although there are different dialects of SQL, it is
nevertheless the closest thing to a standard query language
that currently exists. In 1986, ANSI approved a rudimentary
version of SQL as the official standard, but most versions
of SQL since then have included many extensions to the ANSI
standard. In 1991, ANSI updated the standard. The new
standard is known as SAG SQL.
