MySQL is a database engine that you can use with your web site. 

There are two separate features in the Control Panel.

One allows you to create your databases and assign users while the other feature permits you to edit the database.

How it works:

To create a database, create a name for your new database and enter it into the "Db:" field. Select " Add Db." 

A new database will be created named with your username as a prefix such as: username_databasename. 

Once created, you may manage your database using a pre-installed web based interface named phpMyAdmin by following the link near the bottom of the page.
