Elements in the Design Database
Elements in the Design Database
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. Refer to Database Navigation and Query Syntax for further information on database concepts.
The following chapter shows the hierarchy of all the elements available in the Design database.
