Click on a module name to the right to view a diagram of the table relationships for that module.
In the diagram, the rectangles represent tables. The name of the table is bolded at the top and the primary keys for the table are in smaller type beneath the table name. Click a table entity to see a description of the fields on that table.
The connecting lines indicate relationships between the tables. The fields used to join the 2 tables are printed at the juncture of the line to the table or near the line itself.
