15. ID-Dependent Relationships: The Archtype/Instance Pattern
The archtype/instance pattern occurs when the ID-dependent child entity is the physical manisfestation (instance) of an abstract or logical parent:
PAINTING : PRINT
CLASS : SECTION
YACHT_DESIGN : YACHT
HOUSE_MODEL: HOUSE

16. ID-Dependent Relationships: The Archtype/Instance Pattern
Note that these are true ID-dependent relationships - the identifier of the parent appears as part of the composite identifier of the ID-dependent child.
