DB admin is a simple WordPress plugin that enables to edit tables of the WordPress database in a user-friendly way right in the admin site. It helps openness of your WordPress site and collective work. An administrator of the site specifies which tables are to be editted by editors. Usage is then similar to phpMyAdmin; with DB admin you are restricted to add/delete/update entries to tables in the WordPress database only, though.
This plugin may be useful for developing other plugins, as editors may simply change their settings and content.
