Research And Realization On PDM System Oriented To ASP

Along with the PDM technology's further development, it already no longer was the sole data management system, but is the enterprise information integration public platform, becomes the core technology of the enterprise information integration. Economic globalization and Integration of regional economics make enterprise's information distributed and constructed differently. It becomes a focus for research on informatization of manufacturing industry how to make use of present and advanced information technology to realize enterprise's information in coordination and the sharing of enterprise's information.In this thesis, ASP-PDM is studied on the basis of the research of workflow technology, the dynamic alliance Network manufacture around the world. An application example about ASP-PDM is given based on Web technology and Web Services. The author's main workings are given as follows:(1) System integration research based on Web Services technology. Based on an intensive study of Web Services technology, the article mentions a solution that distribution, isomerism PDM system is integrated.(2) Distribution solution research based on Web technology. The article puts forward a solution that enterprise's information is in coordination and the sharing.(3) System structure based on Web Services technology and Web technology. The article brings forward ASP-PDM System structure.(4) ASP-PDM Security research. On the basis of analysis of present several kind of security mechanism, ASP-PDM security mechanism is given combined with ASP-PDM practical situation.ASP's rising promotes recent development of the advanced manufacture technology and new pattern. Service businessman hire the application software and the correlation hardware long-distance through the Internet net for the customer, utilizing centralized management facility offer to customer , employ , dispose , deposit, product design calculate with drawing , message and resource management ,etc. visiting , services and provides a set of applications solution by thelow operation cost. The user does not need to purchase the software and hardware, only must pay the ASP service gold, may obtain an entire set of advanced enterprise information equipment. The Internet development and enterprise Intranet construct the construction to provide an ideal joint operation environment for the people. This also causes facing ASP possibly to become. The Web application procedure opened, the cross platform characteristic as well as the ASP inexpensive use price causes facing the ASP-PDM system already to become the first choice of mid- and small-scale enterprise and the enterprise dynamic alliance carrying on the joint operation.
