Squash TM Physical Data Model updated

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.
