【摘要】 不同系统之间进行产品数据集成是全生命周期产品数据管理的关键问题,基于XML研究了CAD与PDM之间的产品数据集成。分析了CAD与PDM数据模型之间的关系,得出了XML与RDB之间数据集成的结论;在此基础上分析了XML与RDB对数据存储的优缺点,进而研究了从XML到RDB之间的数据存储及映射关系。最后,基于所研究的理论,实现了CATI与PLM之间产品数据集成的实例。更多还原

【Abstract】 The data integration among self-governed systems is a key issue of whole lifecycle PDM(Product Data Management).Based on XML,the data integration between CAD and PDM is researched.The relation of data model between CAD and PDM is analyzed,the conclusion that data integration between XML and RDB(Relational Database) is made.Secondly,the advantage and disadvantage of data storage of XML and RDB is analyzed,and the data mapping between XML and RDB is researched.The proposed theory is implemented to realize the product data integration between CATIA and PLM.更多还原
