Abstract

We present an extension to the object model of OMT to cope with bottom-up database design. By investigation, it was discovered that OMT as it stands is inadequate to capture some real world semantic and structural information needed to perform schema integration for pre-existing databases in a heterogeneous distributed database environment. Therefore the proposed extension, called Integrated OMT (IOMT), was formally defined and an appropriate extended graphical notation was produced as a part of our work. This extended form was implemented and applied effectively using a tool which we call the schema meta-integration/visualisation system (SMIS/SMVS).
