MySQL is an open source relational database management system that can be downloaded and installed for free, or purchased with a commercial license. MySQL is owned by Sun Microsystems, which is a subsidiary of Oracle Corporation.
Thanks to its free and open source nature, this system has become popular with developers, who can use it to power web sites and desktop applications.
