PDM and ERP are the outstanding business management application system.ERP system which is a advanced enterprise management software develops base on MRPⅡ.It has manifested the most advanced management Theroy in the world now,and carries on he overall balance and the global administration.PDM system develops on the foundation file management system which can relate the design,manufacture and analysis.It takes the product as the core.Along with enterprise management technology progress,more and more enterprises started to used PDM and ERP.But in fact, This two softwares have overlapping information and domain including Bill of Material, the components category message, assembly information ,configure information ,workpiece flow and so on.But They belong to two different systems.it lead to they do not share overlapping information.In these information,Bill of Material is the between PDM and ERP most essential combining site and the integrated difficulty.Therefore,it can realize between these two model of software's exchange of information.This topic has studied PDM and ERP integration method.This topic has analysed PDM and ERP integration methods, according to the characteristic of exchange data,posed a theory which use XML to realize information integrated. BOM is a structuring date form.It describe the BOM appropriately.XML(Extensible Markup Language) spring up technology recently years.It has many characteristics:(1)strong data manifest ability.It can manifest complex date by simple form.(2)strong extensible ability.It can extend according to user.(3)strong manifest myself ability.It can realize the date and manifestation separation.Because the enterprise used PDM and ERP are the database system possibly.So as to realize the sharing information exchange, we use XML to take the bridge.Through the programme extract the data from database and insert XML to database by programme,reduce input work load.
