Abstract: As CAD/CAM becomes more and more popular, efficiently managing large amounts of engineering data becomes essential for improving design efficiency and quality. This paper analyses five basic features of product data management and combines them with real industrial examples. Then, an object-oriented product d ata management model is presented. To carry out the model, the paper presents th e architecture of the CAx information management and integration system (CAx-IM IS), and focuses on its core technology, implementation of an object management framework, and discusses the process of realizing the inherent attributes, relat ions, and messages between objects using the object dictionary and storing detai l information about the persistent objects in relation database management syste m (RDBMS). The method provides an effective object management framework for CAx-IMIS.
