Research And Implementation Of The Sca And Esb-based Enterprise Application Integration System

With the rapid development of Internet, the enterprise business range is expanding and their application system is becoming increasingly complex. However, there is a large of redundancy information in each department,information resources can not be shared, and these drawbacks cause poor system business agility. Therefore, to design a loosely coupled and flexible enterprise application integration system which be able to rapidly response to changes in business decisions is becoming an important issue in software engineering field.As a service-oriented architecture,SCA can make business components and transfer protocol, interfaces and implementation separation, it can perfectly solve the problem that there exists tightly coupled among modules. ESB can make service component location and transfer protocol transparency effectively,make it convenient while the enterprises interact with each other, and make it easy when the business is expanded.On the basis of analysis of the traditional enterprise integration solutions, a new framework for building enterprise application integration model SE-EAI is proposed to overcome traditional enterprise integration solutions shortcomings and combine with SCA and ESB technology. The architecture model uses the SCA technology to guide the development of the various service components, achieve the most basic IT infrastructure functions. Through service agency in ESB, message format conversion can be achieved, dynamic routing also can be formated. Conversion is facilitated in business calls between different systems. Dynamic location and seamless integration of services can be realized, and both full use of companies legacy resources and adding new business resources are achieved.Finally, the model SE-EAI is applied to an enterprise management information system to verify its feasibility and effectiveness.
