| As the development of information technology, informationizing has become the core to improve the competence of manufacturing industry. Applied softwares such as CAX,PDM,ERP in manufacturing industry have become an important technology field of manufacturing technique in China, while they are just in a starting stage. Integrated system of applied software in manufacturing industry can shorten production generation period efficiently and accelerate product transfer from design field to manufacturing field.The present application status of information technology in manufacturing industry is analyzed in this paper, and the problems faced in applied softwares in manufacturing industry are expounded. Also the necessity and importance of applied softwares in manufacturing industry are discussed and the integrated method of heterogeneous data is researched. A data exchanging model based on XML which have height generality and expansibility is proposed, and the mapping between XML and relational database and data access of heterogeneous data are also studied. An architecture of data exchange is given, which is used as the guiding model and basic principles of integrated development system. This system provides a middle-platform of heterogeneous data exchange and sharing, and it realizes transparent operation and seamless integration of heterogeneous data.Based on the above guiding model and system architecture of integrated development system, the applied softwares PDM and ERP are taken as an example to describe the distinctions and relationships between them. Moreover, through compareing and analyzing three methods of integration of PDM and ERP, solution scheme and implementation method are proposed and the integrating and sharing of data between PDM and ERP can be realized. The solution scheme which proposed in this paper has universality, it can solve the data sharing problems of other heterogeneous database applied softwares in manufacturing industry efficiently. |
