The Research Of Enterprise Application Integration Based On Event-Driven & SOA

Now the development of software is accelerated by Service Oriented Architecture. These enterprise applications, which can't adapt the dynamic environment, will lose functions gradually, even to those business process manager systems that face to demand change frequently. This paper aims at propelm of the current study of enterprise application integration that includes ignoring business process intergration, integrated ability is bad, flexibility is poor, and interoperability is not very well and so on. So we propose Enterprise Application Integration manage system based on SOA and Event-Driven - SE-EAI(Service & Event-Enterprise Application Integration), which is advanced in loose-couple, low cost, high integration ability, etc. The main topic of this paper is about the architecture of the EAI based on SOA, it's model and the service.At first, a systematic survey of EAI Management research is given, and then the study objectives of this thesis are presented.Secondly, we analyze the excellence and shortcomings of the traditional technique of EAI. Then we propose the chanlage and difficulty faced by EAI. We combine the advanced technology: SOA and EDA, then we propose the architecture of the Event-Driven EAI based on SOA, which can support the modern flexible enterprise IT infrastructure and show the reuse and flexility of this system.After defining and classing the enterprise application service, we propose the service layer model in SE-EAI, including Application Interface layer, Application Intergration layer, Businss Intergration layer and User Interaction layer. There are application interface service, data intergration service and message service in infrastructure services. Application interface service describes two type of adapter and the model of the adapter. Data intergration service support the data conversion and mapping between enterprise from the formate conversion and semantic conversion. Message service is the communication service. We propose the message model on JMS.Based on these infrastructure services, this paper propose the ECA event-driven model and the business process model, then discuss how to implement business intergration by work-flow. At last considering the requirement of security, we porpose the model of user manage and user sign-on based on PMI(Privilege Management Infrastructure) and SSO(Single Sign-on).Lastly, we applied SE-EAI into the CASCC information integration platform and got some advantages. At last, we give some deep research fields on SE-EAI in the future.
