Corba / Web-based Product Information Management Model Study

Because of the internationalization of the competition and cooperation, enterprises have to expand their markets and form their compact cooperation with using the advantage of resource and sharing the information. The PDM system based on the CORBA and Web technology becomes the development orientation, because it can provide powerful support for the share of the product information and the application integration.On the basis of the analysis of CORBA distributed object model and Web technology, this paper presents the architecture of the product information management system. The integrated product information model based on STEP is established. The database structure of the topic models is inferred through the mapping rule from EXPRESS language to database definition language. And then the Web database access procedure based on the CORBA component is presented. The advantages of the model in developing PDM system based on Web are analyzed and the implementation procedure and method of the CORBA component are detailed described. The application integration procedure based on the PDM system is presented and the attempts to develop the interface between PDM and CAD are performed. Finally the prototype system is introduced simply.
