Check out the ajax-ified Turbodbadmin, an ajax-powered riff on phpmyadmin. It’s got a ways to go to reach feature parity with phpmyadmin but it’s already worth checking out, and it has a sure chance of displacing it once it’s ready for primetime. If you’re not familiar with it, phpmyadmin is a web-based management tool for MySQL databases, and turbodbadmin is basically the same thing with a much nicer and more responsive interface.
