16. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 5-16 ID-Dependent Relationships: The Version/Instance Pattern This occurs when an instance of the ID- dependent child entity is the physical manifestation of an abstract parent: –PAINTING : PRINT –CLASS : SECTION –YACHT_DESIGN : YACHT –HOUSE_MODEL: HOUSE

17. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 5-17 ID-Dependent Relationships: The Version/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.

18. DAVID M. KROENKE’S DATABASE PROCESSING, 10th Edition © 2006 Pearson Prentice Hall 5-18 ID-Dependent Relationships: The Version/Instance Pattern Note the use of weak, but not ID- dependent children.
