Event-Driven Pub/Sub Module Research And Implementation Lei TONG (Computer Applied Technology) Directed By Prof. Guo Zhong DAI

Today information systems are becoming more and more popular in enterprise applications and research on real time data integration has very important value in theory research and application. In this paper, we propose Event-Driven Pub/Sub module. It is based on the research of the existing pub/sub system and the enterprises' real time data integration modules using close-synchronization random Petri net. Now the original system design and implementation has been finished and has been implied into flow-industry real producing process.The main work of the thesis includes:1. The importance of enterprise process data integration was Analyzed, and the shortcomings of exist methods in process data integration were concluded, then the merits and shortcomings of the pub/sub module were analyzed. The Event-Driven Pub/Sub concept was proposed and implied into real system model. The new model can guarantee the QOS parameters for the implement.2. The features of enterprise process data integration were analyzed, the merits and shortcomings of exist process data modeling methods were concluded and the close-synchronization random Petri net modeling method was proposed. The event-service model storeroom and the pub/sub system model storeroom were built based on the model, and the extended implements are supported.3. The Event-Driven pub/sub original system is finished and it is used in the application of the Sinopec MES.The applications show that our method can settle the existing real-time and QoS problems in real time data integration and runs well. It can also earn some economics benefits for flow-industry. Moreover, it can be applied into other trades, such as the scatter industry.
