Abstract
The entity-relationship (E-R) approach is a widely used technique for the semantic modelling of commercial database systems. This paper demonstrates that the ER method can also be applied in the modelling of static design knowledge for knowledge-based engineering design systems. It presents the basic definitions of the E-R data modelling method and describes some extensions which are useful to model the functionality of system components. It demonstrates the use of this method to produce a generic model of a centrifugal hydraulic pump, which is being used in the implementation of an object-oriented intelligent CAD system. Finally, conclusions on the suitability of the entity-relationship for engineering knowledge representation are drawn.
