Abstract
This paper addresses the issue of combining object-orientation with relational database technology. It is an attempt to clarify the difficulties faced by developers when such a combination is used. The object-oriented model and the relational model, and their ontological assumptions are investigated and different approaches to combining them are described and elaborated. The discussion is mainly carried out at a conceptual level, although related technological issues are mentioned where appropriate.
