Abstract: 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.
