EAI Based On Web Services And The Application In The Network Manufacture

Currently, the information technology was applied in many fields. Network economy has become a necessary part of our life. But a lot of legacy systems supported by IT were unshared.The background of this thesis was an important item of science institute automatic called digital intelligent manufacture equipment and system technology. Based on the equipment manufacture field in ShenYang, the EAI technology research was carried out. A demonstration validation has been done aimed at the application- vehicle matter flow management system.This thesis mainly aimed at the problems above, combined with XML technology, SOAP protocol and Web Services architecture, a matter flow system A2A integration framework was put forward based on the integration mechanism of some mature production.This framework adopted the service-oriented EAI idea, based on the Web Services architecture, can resolve the tighten-coupling problem existed in the traditional EAI method.At the same time, the framework can be extended. It is easy to add other applications to this framework without great modification. It is propitious to the B2B integration.The concept and developing status of EAI were discussed at first, and the theory foundation of the EAI framework based on Web Services was given, then the actuality of the vehicle matter flow management system was analyzed. On the basis of this foundation, a whole structure of the service-oriented integration framework was given, three aspects of key realization technology, the definition and transition of messages, the description of the function in the legacy application, the transfer of the integration component, were discussed in detail.At the end of this thesis, the summarization and prospect was given.
