Quick Question about the 15 minute RoR Blog Demo

During the presentation on the RoR demonstration within the RoR website, the presenter who is using a Mac w/ Textmate opens a program where he edits a database table. I am not familiar with what application is being used.

Can you give me more details as his workflow is really nice?

Specifically, I'd love to know what GUI dbase app the presenter is using, this has been made difficult by the fact that the menu's and taskbar are hidden.

Please help.

I believe he's using CocoaMySQL, but there are also Navicat and YourSQL which do the same sort of thing.
