Integration of Behaviour Models

View integration is the most effective technique for developing a conceptual database model. The universe of discourse is described from the viewpoint of different user groups or parts of the system resulting in a set of external models. In a second step these models have to be integrated into a common conceptual database schema. In this work we present a new methodology for integrating views based upon an object oriented data model, where we concentrate on the integration of the behaviour of objects, which is already not supported by existing view integration methods.
