Database Structure Documentation

We have DB model documentation online available in two formats, both of which are auto-generated with each release:

• Our own format (see also SQL Diagram creation)
  • There is a diagram for the Accounts Payable sub system
    • We need volunteers do design more diagrams! Please also have a look at the old 2.1 diagrams (download 9 png files in a zip file).
• SchemaSpy format
  • features quite nice automatically drawn relationship diagrams once you select a certain DB table. That can also be shown for the whole DB if you simply go to the ‘Relationships’ Tab on the index page (though that diagram is HUGE as the OpenPetra DB currently holds >300 DB Tables!).

• Base and Demo databases
