Design and implementation of an extended relationship semantics in an ODMG-compliant OODBMS

In this paper, we propose a powerful `part-whole' relationship model, which naturally extends the ODMG-3.0 object database standard. The proposed relationship model can support almost all of the relationship functionalities existing in the contemporary relational database model and the object oriented data model. In order to design and implement this relationship model, we seamlessly extend the ODMG-3.0 relationship using the inheritance concept. Also, we identify several possible run-time anomalies in implementing the relationship and provide solutions for their problems.
