Abstract

During the development of an object-relational application we combine technologies that make use of object and relational artefacts because each is suited to a particular role. However such a combination of technologies gives rise to problems of an object-relational impedance mismatch. In this paper we highlight these problems arise not just because of differences in language or design objective, but because the semantics and data of an object and a relational artefact are not equivalent. We introduce a novel technique based on equivalence, and use this to explore one problem of an object-relational impedance mismatch. We show that strategies for dealing with the problem of identity should not focus on a correspondence between the two identity systems but on a correspondence between the different ways in which the identity of an entity has been represented.
