A critical step towards computer integrated manufacturing CIM is the integration of computer-aided design CAD and computer-aided manufacturing CAM. Well developed CAD, CAM, and Business data processing systems generally exist in an organization. These systems represent years of work and a very large investment for the organization. Thus a necessary condition for integration is defining schemes through which existing engineering and non-engineering data can be represented and manipulated in an integrated way. In this paper a Common Data Model CDM approach to distributed heterogeneous database is adopted for CAD/CAM integration and an Extended-Entity-Category-Relationship EECS Model an extension of ER model is proposed. The use of EECR model as a common conceptual data model for representing engineering and non-engineering data is discussed.
