Abstract:To solve the actual problem of the distribute collaborative design between the enterprises, Web application of PDM software system based on C/S framework is studied. A four-layer framework model of PDM system based on Web is analyzed, focusing on the difficult points such as the heterogeneity of application software、information transmission and so on in the process of Web application of PDM software based on C/S framework, according to the four-layer framework model and WCF communication platform, universal PDM system application is designed and built with PDM software based on C/S framework. Meanwhile, PDM database is accessed by ADO.NET, and according to the sectional-type data access in the way of querying the table structure and primary key information by table name, the sectional-type Web transmission of mass PDM data based on C/S framework is achieved.
