In order to realize effective process management and application integration used in the whole product development process, some advanced techniques or methods have been proposed and successfully applied in product design. But in distributed environment, how these engineering tools can effectively access right data in right format at the right time inevitably becomes a very important factor in product development. So a flexible integrated design platform for process integration has been established, which consists of representation layer, process control layer, services layer and repository layer. Based on analyzing three patterns of organizing data, context data model is introduced, which organizes data based on process. The mechanism of interaction between context data model and process unit is described in detail. The model-view-controller (MVC) design pattern is adopted in our design platform which separates data model from its various views. Web services are developed to realize the dynamic data integration between applications. The design platform based on the key techniques is developed as a prototype to prove the concept.
