Database Schema for Jahia

[CodeMonkey]

I am looking for a database schema for Jahia 4.0.5 (if it exists).  I 
have searched around the newsgroup - the only mention I could find was a 
pointer to this location: http://www.jahia.org/jahia/page371.html which 
doesn't seem to exist any more.  I have also tried DbVisualiser to no 
avail (no foreign key relationships).  Is there any reference 
documentation out there?

Cheers
