The objective of this company is that MySQL meets the standard SQL, but without sacrificing speed, reliability or usability.
Michael “Monty” Widenius in the 1990s tried using mSQL to connect the tables using low-level ISAM routines, but mSQL was not fast and flexible for your needs. This led him to create an application programming interface called SQL to MySQL database very similar to mSQL but more portable. The name comes from MySQL combined My daughter Widenius, the acronym SQL (according to the documentation of the last English version). Moreover, the base directory and many of the libraries used by the developers had the prefix My.
