MythTV uses a MySQL relational database to manage almost all aspects of configuration and day-to-day operation. Mythfrontend, mythbackend, mythfilldatabase, MythTV plugins and ancillary programs all interact with the database and use it to store settings and information.
Command line interface
Use the mysql command on the host running the database:
% mysql -u mythtv -pmythtv mythconverg
SQL commands can be issued at the mysql> prompt.
Try installing phpMyAdmin.
