Research Of Product Data Management System Based On Extranet And Component

This paper briefly presents the research and implementation of Product Data Management(PDM) system based on Extranet and component.Generally speaking, Product Data Management(PDM) system, being a kind of software which is designed for the purpose of dealing with products' data and R&D procedures, has its disadvantages. In my opinion, the disadvantages of PDM are as follows: in the beginning, PDM cannot run efficiently in the procedures of the products' promotion and utility, also it has little help for customers. Furthermore, other characters which do not run as what we wish it to be are reliability, maturity, usability, maintainability, portability and so on.To solve the above problems, the design thinking of Product Data Management(PDM) system based on Extranet and component is presented in this paper.In the PDM system based on Extranet, information of products can be shared easily and conveniently not only in Intranet but also outside Intranet.In the PDM system based on component, much attentions have been attached in segregation of functional model from the procedure of requirements analysis. The components, which are designed on the basis of these functional models, can be divided into four types: elemental component, common component, component for special utility and component for management and supervisors. The components for special utility, which are fabricated from common components, are the core of our Product Data Management(PDM) system. Only by using the components for special utility, can we put all requirements from industrial fields into practice.In this paper, the key technologies, which are relevant to the research and implementation of Product Data Management(PDM) system based on Extranet and component, such as database design and means for improving the data transmitting efficiency are also detailed.The industrial field experience shows the design of PDM system based on Extranet and component is reasonable and feasible. This PDM system can not only be used in paper making industry but also in other companies.
