Researh of B2B E- business application & development technology based on Web services

Today, the B2B E-business systems in most enterprises usually have multiple heterogeneous and independent systems which are based on different platforms and operate in different functional departments. To deal with the increased services in future, an enterprise needs to expand its system continuously. This, however, will cause great inconvenience to the future system maintenance. To implement E-business successfully, a unified internal E-business integration environment must be established to integrate the internal system and thus realize a unified internal mechanism within the enterprise E-business system. The SOA (Service Oriented Architecture) architecture, however, can well meet the above requirements. The integration of SOA- architecture-based applications can reduce the dependency of different types of IT systems, reduce the cost of system maintenance and the complexity of the IT system operation, increase the flexibility of the system deployment, and at the same time exclude the barrier of service innovation. Research and application of SOA-architecture-based enterprise application systems has become a very important research project at present. As an important SOA implementation, Web services is a relatively new technology widely accepted by people. This is because Web services provides a distributed computing method for the heterogene- ous applications integrated in the Internet. It can integrate the applications running on the distributed servers which are connected through Intranet, Extranet, and Internet together. Based on SOA, this document designs an enterprise E-business application model and realizes a flexible and expandable E-business platform.
