Research And Application On Heterogeneous Data Exchange For Collaboration Platform Of The Automotive Industry Chain Based On XML

The platform of Auto parts Collaborative Enterprise is a large-scale distributed cloud platform which is geared to the needs of car manufacturers, parts manufacturers, car dealers, spare parts dealers, after-sales service etc. The cloud platform which provide business process integration and a variety of collaboration information systems interoperability on the manufacturing industry chain. And it integrates tens of thousands of enterprise information systemsBut in the process of the platform and the enterprise existing information system integration, the problems of heterogeneous operating system, data management system caused the heterogeneous data with huge amount of data. How to realize the information interaction between heterogeneous data has become a problem. At the same time, the data is transmitted in the network can be obtained or tampered and other security risks that increase the difficulty of data sharing. Therefore, to further ensure the safety of the heterogeneous data, the integrity of the data exchange technology to solve the heterogeneous problem of data exchange in the cloud platform is of great value and significance.Firstly, this thesis focus on analysis and study on the characteristics of heterogeneous data when collaborative cloud platform of automotive industry chain between automobile enterprise information system sharing data information or integrating data resources. In order to achieve sharing of information resources between the auto companies, at the same time to ensure information systems security, this thesis make full use of the advantages of XML on heterogeneous data exchange, combined with Web Service technology to build a cloud platform for multi-source heterogeneous data exchange model for the goal as which the demand of heterogeneous data exchange on cloud platform. This paper focuses on the analysis of the conversion between relational database and XML document, According to the constraint conditions of tables in relational database dynamicly configurate data exchange control file. Under the supervision of data exchange control files this system through invoking a Web Service interface to upload data and download data; at the same time in order to guarantee the security of data exchange, use many kinds of technology, such as authentication and IP recognition on Web Service interface to enhance the security of data. And this thesis uses AES encryption algorithm combined RSA encryption algorithm to protect the data security when data transporting on the Web. Considering the instability of the network. But we have to ensure the integrity of the data, this thesis not only transmitted data compression process, also proposed data based on XML and Web Service technologies retransmission model which can be certainly ensure the integrity of data when transmission. Finally, this Data exchange system use the bulk insert method of ADO.NET technology to achieve rapid exchange of heterogeneous data. At last, this thesis verifies the practicability of multi-source heterogeneous data exchange security model, find it achieved good results.
