MariaDB is a community-developed
fork of the
MySQL relational database management system, the impetus being the community maintenance of its free status under the
GNU GPL. As a fork of a leading open source software system, it is notable for being led by its original developers and triggered by concerns over direction by an acquiring commercial company
Oracle.

The intent is also to maintain high compatibility with MySQL, ensuring a "drop-in" replacement capability with library binary equivalency and exact matching with MySQL
APIs and commands.
[7] It includes the
XtraDB storage engine as a replacement for
InnoDB,
[8] as well as a new storage engine,
Aria, that intends to be both a transactional and non-transactional engine perhaps even included in future versions of MySQL.

Its lead developer is
Michael "Monty" Widenius, the founder of MySQL and Monty Program AB. He had previously sold his company,
MySQL AB, to
Sun Microsystems for 1 billion USD. MariaDB is named after Monty's younger daughter, Maria.
