A Data Manager for Engineering Applications

Efficient data management is crucial to the success of a CAD/CAM system.Traditional database systems,designed to deal with only regular and structural data,cannot efficiently manage design data. In this paper,we present a data manager called EDBMS/2,which has been developed by our laboratory for engineering support applications.EDBMS/2 has a data model that combines features of both relational and semantic ones and owns flexible abilities for modeling engineering data,such as variable-length data processing…
