Mapping Database Models to DDLs
Chapter 6 described ORN Additive, which extends the SQL Server RDBMS with ORN. Chapter 7 described OR+, which extends the Object Store ODBMS with ORN. Both chapters presented an example of an ORN-extended class diagram that modeled a company database. Chapters 6 and 7 also gave DDLs that implemented the model as an ORN-extended RDBMS and ORN-extended ODBMS, respectively.
