Objects in a PDM
A physical data model diagram contains table symbols to depict database tables and constraint lines to depict the relationships between tables.
This graphic is described in the surrounding text.
Note Each Physical Data Model diagram is self-contained and independent of any other PDM in the encyclopedia. Tables and constraints belong to a specific PDM. Therefore, many PDMs can have a table named Customer, and each of those tables named “Customer” might have different columns, indexes, triggers, and so on.
