I'm a bit disorganised with things at the moment. I'm kinda developing this site in an ad hoc manner which is probably a bad idea so I'm trying to fix up a few mistakes I made early on. In terms of the database I've just added new functions as needed which I use instead of direct SQL in my Python code. Maybe I should sit down with Visio and try and do a diagram before I go any further? I'll just write a simple script for backup and restore and call it before each test run but have the schema only dump come from production. At this point it doesn't really matter as the website is so small. Simon.
