MySQL is a widely used open-source database. It is the default database type installed on all cPanel servers. Databases such as MySQL are often used to store data that web scripts need (like user information or forum posts), because they make storage and retrieval a simple process. Although MySQL is considered an open source database, it has a separate license for commercial use, and so some commercial products may be required to purchase a license.
