Business Process-oriented Service Composition

Enterprise Information Integration settles the problem of "Information Island", and still requires further development in the field of integration based on business process. Service-Oriented Architecture (SOA) proposes a Service-Oriented Business Process Integration framework. How to expanse ESB platform, implement the service composition and integrate business process is of vital significance. The service-oriented process management in this paper, which is integrated on ESB platform and based on JBI implantation, is loosely coupled. It has the advantages of unified standard and accord with the new generation of business process integration with the main trend.This dissertation researches deeply the software system's service-oriented architecture and the implementation of standard ESB based on Java technology. Based on the platform of SynchroESB, it begins to analyze mechanism for assembling services, then compares the business processes and rules description language, finally designs and implements the service composition model which we present in this paper, adopts BPEL and Drools as the modeling languages for business process, designs the service components implemented business process, encapsulates the third-party software as the BPEL engineer and inserts it into the JBI environment to execute process. Meanwhile, we propose a management module based on JMX can monitor and control the running process instances and processes' history data.This ESB software system based on the service composition model not only carries out the function of information integration, but also contains the implementation of business process management and activity monitoring. Our software is designed and implemented following the related implantations but also accord with the popular industry standards. It's high capability and reliability guarantees the product's market prospect. So, we believe it will have a good market prospect.
