The Research And Implementation Of Transaction Processing In Public Information Service Platform Of Civil Aviation

With the sustained economic development and continuous improvement in people's living standards, service quality of public transport changes to be very important. However, in current situation, the development of information service for the public and the industry-wide data sharing cannot adapt to the rapid development of civil aviation of our country. There are many difficult issues, such as legacy systems integration and business process management.The legacy systems can be integrated by the applying of Web Services. Transaction processing is a reliable basis for applications. The transaction processing based on Web Services is a critical technology and difficult issue of research. The research of system architecture based on services makes great significance on high performance and high reliable applications. This paper proposes a coordination framework of transaction processing based on Web Services. This framework applies the transaction model which supports function substitution, and the concurrency control coordination mechanism based on conflict sphere. So the problems on system integration and business process management are solved partly.At first, starting from the summary of coordination mechanism of traditional transaction and distributed transaction, an atomic transaction model is introduced. According to the features of long running transaction based on Web Services, this paper proposes the cohesion transaction model which supports function substitution, and analyzes its attributes.Secondly, a transaction processing coordination framework which is presented in this paper applies the transaction model which supports function substitution. Meanwhile, according to ACID of Web Service and WS-Tx, this paper brings the concurrency control mechanism based on conflict sphere and improves WS-BA and WS-C. This mechanism achieves its function with the attributes of shared resources.At last, it is the design and implementation of the framework. Transaction model, concurrency control mechanism and the coordination framework have theoretical significance and engineering practical value. They apply to civil aviation public information service platform.
