An enhanced data model for CAD/CAM database systems
Abstract
The record-based conventional data models have been criticized as not powerful enough to model a complex data domain of CAD/CAM. This paper proposes a Semantic Network plus Model (SN+M) as a data model for an integrated CAD/CAM database system. The SN+M basically is a model coupling semantic network capability developed in artificial intelligence and relational table capability developed in database in order to naturally accommodate the features of a complex data domain.
In this paper, we first discuss 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+M data model concept is then briefly discussed. We then discuss on how the proposed model can be used adequately and naturally to model some of the important and representative information of CAD/CAM data domain. Finally, a conclusion is made to summarize the major advantages of the proposed use of SN+M as compared the use of conventional data models.
