Object Relater , (OR+)d the Object Database Manipulation Language (ODML). These languages extend and imitate an ODMG standard for object databases (Cattel et al. 2000, 1997). Adding ORN to ObjectStore increases the productivity of developing object database systems and improves data integrity in these systems. Implementa

Association Semanticsleties. These subtleties can lead to associations and combinations of associations that may be mathematically inconsistent or ambiguous. With a modeling tool, like the ORN Simulator, association semantics can be fine-tuned and any inconsistencies or potential ambiguities can be detected by database

Adding ORN to the ODMG Standard for ODMSscapabilities like concurrency control and recovery to manage access to these objects. An ODBMS, one type of ODMS, stores the objects directly in an object database. An .

Mapping Database Models to DDLs 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.
