All data in the Design database is stored in elements in a strict hierarchy. Every element has a type and each type determines the attributes available on the element. For more information on database concepts, refer to Database Management Reference Manual.

The following chapter shows the hierarchy of all the elements available in the Design database.

Design Database Hierarchy - Top Level
