NEW: Looking for the Joomla 1.6 database schema?
It’s right here: Joomla 1.6 database schema.
Continue to read about the 1.5 schema
Joomla 1.5 beta is just around the corner now. Jinx has earlier stated that it would be released before may but we are yet to see if the core devs manage to keep their promise. As part of my involvement in the standards & guidelines group in Joomla, I set up a Joomla database schema to give 3rd party developers a clearer understanding as to how the core database is structured. Click the thumbnail to the right to see the full sized schema.
The diagram also has column info expanded, so that you can see the column types (varchar, integer, etc). This makes the schema a bit messy, but this is a feature you easily can turn on/off in DBDesigner to make it more readable again.
