Application of SOA and Web Service in Implementing Heterogeneous System Integration

Large enterprises tend to have heterogeneous systems, namely the formation of "islands of information", that makes information interaction and interoperability very difficult. Application of integrated development based on service-oriented architecture, which does not change the underlying architecture of enterprise applications, is a good solution to the aforementioned problems. This paper proposes a scheme to integrate heterogeneous resources based on SOA and Web Service, and builds inter-departmental business systems to conduct feasibility analysis and to verity theoretical basis with interoperability, cross-industry interconnection and data sharing as benchmarks.
