An enhanced data model for CAD/CAM database systems

The author proposes a semantic network plus model (SN/sup +/M) as a data model for an integrated CAD/CAM (computer-aided-design/computer-aided-manufacturing) database system. SN/sup +/M basically is a model coupling semantic network capability developed in artificial intelligence and relational table capability developed in database management to naturally accommodate the features of a complex data domain. He discusses some of the special features of a CAD/CAM data domain which make it very desirable to have a higher-level data model. The SN/sup +/M data model concept is then briefly discussed. He also discusses how the model can be applied to some of the important and representative data of the CAD/CAM domain. Finally, he summarizes the major advantages of SN/sup +/M as compared with conventional data models.<
