The Design And Realization Of Auto Mall Data Exchange System

Data exchange system is used for data integrate and exchange by heterogeneous systems, which to achieve integration and sharing of data in a distributed heterogeneous systems.With the depth popularity of automotive internet,automotive industry media, dealers and manufacturers have developed web systems. Competition of user web browsing become increasingly intense between distributed systems, which lead to potential car users information will be integrated by manufacturers. It is to ensure maximum manufacturers follow up, maintain and promote the entire transaction process is completed for potential car users. For automotive internet problems of "Islands of information", SOA was adopt in this paper, and big data of automotive network was used base on architecture of the C/S, and data exchange system of auto mall was designed, and data exchange of heterogeneous systems was achieved. The research contents mainly divided into the following several aspects.Firstly, the data exchange technology and principle was studied, the Web Service of oriented interface services was chose, and the data was transported by HTTP protocol. The encryption of Triple DES was used for user to authorize and verify. Monitor system of Email was built to ensure security and privacy of the data exchange and transmission. JSON was used as a data format, and XML of structure document format was improved to solve bottleneck low efficiency transmission. Interface using Triple DES algorithm in order to give the interface call object authorization and authentication, and set up exception email brush prevention guarantee mechanism and interface technology, to ensure the security and privacy of data transmission and exchange. In the way using the JSON data interchange format, and improved the structure of the XML document format in the bottleneck of data transmission efficiency is low.Secondly, according to the characteristics of professional automotive network data, the data similarity matching was realized using the principle of cosine theorem. Heterogeneous data was match automatically by the system, and the efficiency of the data mapping was improved, the cost of artificial matching data was saved.Thirdly, the queue mechanism and timing retransmission technology was used to solve the system integrity and reliability. It is result that the method is effective. At the same time, the timing system and instant transfer was used to solve the timeliness of data transmission.
