To help you to work with the Squash TM database, you will find here the Physical Data Model (PDM) for version 1.20.x, using UML conventions. For readability reasons, this is a simplified version. Only tables and significant links are represented. It will help you to understand how the Squash TM database works. As a reminder, a PDM is a graphical representation of the tables of a database, with the links between these tables. This PDM is available in PNG and PDF format, on 1 or 6 pages for your convenience of viewing on screen or for printing, depending on how you want to use it.
