Symantec Management Console SQL Queries

Hello Guys,

I am currently a student apprentice and my task is it to create Reports with the Symantec Management Console. My Problem is that there is no Database Schema where i can see how the tables are connected.

Now I am trying to make a Drilldown Report , where I am clicking on a Client and want to see all Software packages that are deployed to this client.

My problem is, that I dont know which tables I have to join to get the related Information i need.
