Moodle Adminer is a useful database administration tool. It works with MySQL, PostgreSQL, Oracle and MSSQL. When installed as part of Moodle, it becomes part of the Moodle interface and a link can be found in *Site administration > Server*.
This is a powerful program that should be used with care and be available only to trusted administrators.
Adminer is available for download from the Moodle plugins directory: [http://moodle.org/plugins/view.php?plugin=local\_adminer](http://moodle.org/plugins/view.php?plugin=local_adminer)
Anyone using PHPMyAdmin is recommended to switch to Adminer.
