Today, the development, sale and post-sales services of a product can normally be finished by different enterprises cooperatively, because the division of labour is more and more thin. This lead to the more cooperation and information interaction between enterprises or the internal of a enterprise to expand gradually. The application of PDMS resolve information interaction and shaving problems between the internal of hhe enterprise to a certain extent, however, there are still information sharing problems, so, it is the key technologies that integrates the data of PDM systems between enterprises, and how enterprises interact information becomes the hot point in the field of PDMS application.The paper mainly researches on the data integration methods between multi-PDMS, also the data replicating method and schema integration method, then analysis the advantage and disadvantage of the two methods, finally puts forward the key problems in the data integration. This paper also researches the framework of web services and related technologies and then analyses the feasibility of introducing the web services into date integration methods. Through the analysis this paper puts forward a date integration method between multi-PDM based on web services, which combines the two methods organically, it can resolves the key problems in the data integration, such as autonomy of data sources, flexibility of the integration method, transparency of user accessing and so on, and on basis of this method. The paper puts forward system model of the data integration between multi-PDMS based on web services and then presents the function modules and implements the main modules.The purpose and significance of this research is to give users a better date accessing services between multi-PDMS, resolve these problems such as low transparency of user accessing, poor flexibility of the integration and so on, expands the information interaction and sharing, shortens the product development cycle.
