Multi-user view integration system (MUVIS): an expert system for view integration

A description is given of the architecture and development of a knowledge-based system called MUVIS (multiuser view integration system) to support the design of distributed object-oriented databases. MUVIS is implemented using an object-oriented development environment. It assists database designers in representing user views and integrating these views into a global conceptual view. The view integration component is decoupled from the view modeling component. The underlying data model, the semantic data model, treats all parts of the design as objects, thereby reducing the complexity of the integration
