About MySQL
SQL is a special-purpose programming language designed for managing data,
held in a relational
database management system.
SQL was initially developed at IBM by
Donald Chamberlin
and
Raymond Boyce in the early 1970s.
SQL consists of a data definition language and a data
manipulation. The scope of SQL includes data insert, query, update and delete, schema creation and modification
and data access control. Although SQL is often described
like a declarative language, it also includes
procedural elements.
MySQL is the world's most widely used open source relational
database management system that runs as a server providing multi-user access to a number of databases.
It is named after co-founder
Michael Widenius's (photo) daughter. The MySQL development project has made its source
code available under the terms of the
GNU General Public License, as well as under a variety of proprietary
agreements. MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB,
now owned by Oracle Corporation. The popularity of MySQL, is due to the fact that is very used in
combination with PHP.
MySQL is a popular choice of database for use in web applications, and is a central component of the widely used
LAMP open source web application software stack. LAMP is an acronym for "Linux, Apache, MySQL,
Perl/ PHP/
Python".
Free-software-open source projects that require a full-featured database management system often use MySQL.
