Research And Application Of Integration Approaches Based On SOA

Currently,Enterprise information has developed rapidly along with the economic construction.However,enterprises also have accumulated many isolated application systems which lead to serial "information isolated islands", so integration of these applications is becoming the utmost needs of enterprises today.Under this situation,service-oriented architecture is developed. Meanwhile,the maturity of service component architecture, service data object and web services technologies provide the technical support for enterprise application integration.The thesis proposes a new solution of enterprise application integration based on the service-oriented architecture.Firstly,it discusses the theory of service-oriented architecture,the technologies of web services,service component architecture and service data object in detail. On the basis of analyzing the integration of the service layer,it makes an in-depth study of the enterprise application integration based on the the service-oriented architecture.It analyzes the principle of application integration based on web services,designs an integration architecture based on web serivices and discusses the advantages of its integration.Meanwhile,it analyzes the application integration based on service component architecture and discusses the advantages for its integration.Secondly,Combining with the analysis of the enterprise application integration based on the service-oriented architecture,it designs an enterprise integration architecture based on service component architecture, service data object and web services technologies.The architecture resolves the problems of service assembly and data programming.It pays more attention to analyze the architecture and makes an in-depth study on the invoking of service component,service composition and match, service component architecture design and strategy, data access service.Finally,it designs and implements the individual housing loan system according to the designed integration architecture.Meanwhile,it analyzes the technical issues in the process of development.
