Abstract

Engineering database management system (EDBMS) is the kernel of CAD/CAM system integration, and object-oriented EDBMS (OOEDBMS) is the best implementation. While STEP is becoming the standard of product data exchange and representation, supporting STEP in engineering database becomes more and more important. In this paper we introduce the architecture of STEP based OOEDBMS in our CAD/CAM integrated system GHCAD. We focus on schema management and three-grade database management in OOEDBMS. Topics such as DDL compiler, transformation from EXPRESS to DDL, DDL tools are discussed. Finally further research directions of schema management in OOEDBMS are present.
