Study Of SOA Based Enterprise Application Integration

Enterprise Application Integration(EAI) has always been attached more importance in academic and industrial circles.However,there are kinds of defects such as hard coding,complex technique and tight correlation in Traditional EAI techniques.The appearance and development of SOA provides EAI a much more perfect solution.The EAI based on Web services has been succeeded in recent years, then makes people pay attention to the integration technique of SOA and has been the hotspot of the research.Although Web services is the most common practice of SOA, they obviously have some flaws.This paper analyzes the disadvantage of EAI based on Web services,with a viewpoint that SOA is a new and complete set of distributed software systems composing method and environment,proposes a solution of Business-Driven Service Component Integration(BDSCI),considering of both business and technique domains. We discuss the basic concept of SOA,introduce the advantage of SCA being the way of SOA implementation at first,then elaborate the relative background knowledge include Service-Oriented Architecture Analysis and Design(SOAD),SCA Specification,SDO Specification and BPEL.On the basis of these,we propose the solution of BDSCI.At first,we research some key question related in the solution and discuss the design of integration model of the BDSCI solution.Then,we elaborate the method of BDSCI,which is composed of different phases include Business Driven Analysis,Service Component Design,Service Component Implementation, Integration and Deployment.Finally,we display the application of BDSCI through Bank's typical cases--Personal Loan Business and Personal House Loan Business.
