Through the analyses of the present situation about metallurgy,it's very clear that the separated information in the metallurgy enterprises can be connected organically and different kinds of data can be highly concentrated,harmonized and shared.It combines the market demands and the practical production as well as the practical production and the management so that the metallurgy enterprises better meet the variety changing market demands.Meanwhile,according to the analyses of security and distribution of COM+ technique,the system structure has been proposed that adopting COM+ technique realizes distributive PDM integrated frame.Some safety setting depended on different roles can be done to some kind of service(or interface method) to ensure the security when the data are shared.Because COM+ service servers can be stored scatterly and the database or data warehouse can also be placed in different computers,the flexibility and distribution of the PDM system have been greatly improved.Therefore,PDM frame based on CDM+ technique can provides very good safe,distributive data share and management.
