Abstract: We present a PDM system which supports the enterprise-wide access to product structure data through the World-wide web (WWW). To meet the needs of various enterprises and types of user, the system is based on a product data model which is both flexible and extensible. The system is implemented using the Object Management Group(OMG) object-oriented database management system and using a Common Object Request Broker Architecture(CORBA) Query Service to access produce data that are in heterogeneous environment. This project deals mainly with extensions of the existing Product Data Management(PDM) system to the distributed networked-manufacturing system.

Key words: distributed networked-manufacturing, product data management, common object request broker architecture
