Abstract


Development of information technology to the enterprise has brought rare opportunities, but also to bring new challenges. Enterprises face various \As traditional systems integration solutions generally makes the whole system more complex topology, component connection protocol is not open, standardized; therefore uses a service-oriented architecture model, the application system abstraction into one coarse-grained services, standardization of services interfaces, loosely coupled services architecture. ESB platform using service-oriented integration with legacy IT systems, the system service-oriented approach through service composition reuse enterprise IT assets, for newly developed information system, with plug means for rapid deployment, reducing the return on investment cycle, improve system adaptability, flexibility and scalability enterprise solutions become \In the past, banks have done the project. Mostly to departments, projects, product-centric. And not focus on the overall development of enterprises. IT projects are usually done well, but the needs of the business is often done when the project fast changes have taken place. Because there is no long-term vision of an enterprise. IT is always lagging behind the pace of building the business changes. Bank building information integration is to go beyond this \This paper first discusses several common application integration approach by comparing the respective advantages and disadvantages and scope summed suitable for large-scale enterprise application integration architecture models and methods. Then, in-depth discussion of the integration methods require significant methodology and framework support SOA, given the basic concepts of SOA, collaborative models, and by analogy with its advantages compared with other architectures. Finally, the paper, based on service-oriented architecture specific implementation of enterprise application integration scenarios. In this paper, \In analyzing the deficiencies of the original integrated system after a set of service-oriented architecture-based system design, in a distributed environment, to create a \And on this basis, further given the solution based on various levels and the specific design modules. Then, how and from early in the project through an iterative approach to system service identification, registration and how to implement the service call, how to process definition and integration, how to implement an ESB-based service management and monitoring, and security processing and other aspects of given system implementation. Since integration of SOA design, based on the new framework of the integrated information system architecture combines the modularity and flexibility, openness and integrity of data structure characteristics, thus ensuring the overall application architecture and data architecture and future all OK Information system architecture design consistency and coordination to ensure that the overall, long-term gains.
