SOA-based Enterprise Application Integration

The increasing of quantity and scale of enterprise applications andthe appearance of Information Isolated Island, has really broughtserious problems and huge challenge of Enterprise Application Integration(EAI)infront of the CIOs. In the traditional solution of EAI, softwaresare closely coupled with each other but this will generate new problemssuch as exposure of enterprise private data-structure etc. All thesedrawbacks can be eliminated by the Service Oriented Architecture. But theSOA has its own flaws which have been emerging as a concomitance of themounting up of services, the complication of inter-service communicationand the relationship between service providers and consumers and thedemand of service compability with future technologies. These flaws makethe service management robe the principal thing in the integration ofenterprise application.This paper, based on the concept and theory of SOA , describes therole and function of WebService and SOA in the EAI. With the analyse andcompare of some actual EAI case, a blueprint of a new , flexible andcomplete architecture have been brought out to solve the problem whichwill probably be presented during the process such as inter-servicecommunication, dynamic service composition, service relationsimplification, universal client calling, transporting and architectureextensibility.The solution is implemented in an "Animation Producing Process andProject Managing Key Technologies Research and Develop(CGProject)" theproblems above are separately detailed in the following chapters in ServerSolution, Client Solution and Mobile App Extension Solution as the mainpart of this paper.In Charpter 4, this paper will detail the technologies used in theproject architecture such as ESB, EDA, Modified Service Register, ServiceGraph, and service composition, the architecture will make the code ofproject more flexible ,have more agility with the demand as an inheritorof old system. In Charpter 5, it will describe the broker of the client partwhich makes service call uniformed and convenient. And as the content in Charpter 6, we present a useful way to make service accessible to mobilephones. And all the content above will be stated as a suitable and effectivesolution for our application integration in CGProject.At last, the author gives out the scarcity of the work and thelooking-forward and also hopes the integration architecture will bemodified and perfect by future study and research in SOA field.
