Aquadata looks like a very interesting application, I'm often surprised that there's so much support for database ddl and querying, but not so much support for actually doing something more with the data, like graphing and other visualisations.

And to plug my own little endeavour :-) if you're on Linux and are looking for a quick and easy to use Forms builder, here's my early beta http://www.data-forms-action.com/

Supports MySQL and Postgres currently.
