The product data management system was the important foundations of product design. The rapid development of information technology such as Web services was widely applied in web applications. Web services integrated the design data and applications that were distributed in the enterprises. Designer could integrate the product design information during the product design lifecycle using web services. This research combined web database and Java language to develop the product data management system. We used the object-orientated programming methodology and UML standard to analysis and model the system, and to develop a solution of stepping the platform and language successfully.
