Research On Transaction Coordination Mechanism Of Logistics Information System

The development of computer science and telecommunications contributes to the informatio-nization of logistics, and enhances the efficiency of logistics management in logistics informationsystem. The application of Web services in logistics information system can help solve the prob-lems resulting from differences in area and system development environment between various en-terprises, achieving seamless integration of logistics systems. Transaction technology can help Webservices guarantee the consistency of operation results and improve system reliability. In recentyears, attempt at solution of transaction coordination in Web services has become a hot issue, whichis also the requirement of enterprise applications.In this thesis, focuses are on the characteristics of logistics information system, and an abstractservice-based Web service transaction coordination model (AS-WSTC). AS-WSTC extends an ex-isting Web service transaction coordination protocol, obtaining the ability to perform internal com-pensation based on forward recovery and to perform external compensation with a compensationinterface. Moreover, the definition of diverse compensation rules allows flexible compensation. Themodel is mainly composed of client, coordinator, abstract service, adapter, and participant. It per-forms compensation according to the compensation rules defined in abstract service, and improvesthe success rate of transactions. Finally, a logistics application instance of AS-WSTC verifies theeffectiveness of the model.
