MySQL is a popular cross-platform, open-source relational database management system (RDBMS). The name of this database is derived from a combination of “My”, the name of co-founder Michael Widenius’s daughter, and “SQL”, the abbreviation for Structured Query Language.
MySQL was initially released on 23 May 1995 by a Swedish company, MySQL AB, founded by Swedes David Axmark, Allan Larsson, and Finland Swede Michael “Monty” Widenius. Development work was originally done by Michael Widenius and David Axmark.
MySQL AB was acquired by Sun Microsystems, which was in turn acquired by Oracle Corporation. MySQL is written in C and C++ with its SQL parser being written in yacc.
