Databases are created and maintained using MySQL. Another MySQL function is to verify credentials and permissions.
First, to initiate a connection to a database, MySQL must authenticate a database user and password combination (as well as the hostname from which the request was made).
Once the connection is authorized, commands to manipulate a particular database are validated. During validation, MySQL checks that privileges have been granted to the specified database for the database user.
The database user privileges need to be granted before MySQL will allow that user to execute the request on the database. MySQL maintains these privileges in its own database table mysql
.
