For a really long time, I''ve been using DBDesigner from FabForce.net.

Hi, I have a ''descriptions'' table which has_one of lots of other tables. The other tables all belong to a description. But I only want each description to have one record from any of the tables.

Hi there, we made a PHP and Impakt2 based web content management system for schools with specific features that work really well for schools. The way I designed it was so there was one central set of source code and an empty (in terms of rows in tables) database structure. To set up a new school i had a script that basically created a new directory in /var/www and then within that, symlinked
