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.

By default, the database is named mythconverg and contains a set of tables that interact with one-another. When running multiple frontends and/or backends, only one database is required.

Database tables

In 0.26 there are 103 tables in the database. The incomplete schema below gives some information about what each table is for and some of the key fields.

Information on the 0.27 database schema generated by Doxygen is available here on the MythTV code development site.

% mysql -u mythtv -pmythtv mythconverg

SQL commands can be issued at the mysql> prompt.

Graphical interface

Try installing phpMyAdmin, which can administrate MySQL databases via a browser.
