The Research On Dynamic E-business Oriented Inter-Enterprise Information System Integration

Inter-enterprise integration is an effective way to bridge the "information islands" between enterprisers' information systems. And the Dynamic E-business is one of the development trends of the enterprise execution. It enhances the collaboration between enterprises and promotes the competitive strength. So, a new method is needed to make enterprises integrating dynamically and easily, and to enable enterprises to find partners in an opened standard way.Firstly, the developing history of the enterprise information system integration technology and the "two-dimension" theory is introduced in order to reveal the real meaning of the inter-enterprise information system integration, as well as its aims and requirements.Secondly, the impactions on inter-Enterprise information system integration caused by Dynamic E-business are analyzed in the point views of run-time environments, dynamic attribute and real-time requirement. And then, sets up a set of aims and principles for building an information system integrating model.Thirdly, A model for inter-Enterprise information system integration in the environment of the dynamic E-business, called SPIDE, is designed by using Web Service technology. The architecture and functions of the model are introduced, as well as the interactions between enterprisers via SPIDE model. The model makes Web Services as basic integrating units to solve the problems of structure difference when integrating enterprisers and its suppliers or partners. And then, describes enterprises participated in integration as service providers and requestors to enable enterprises and its partners finding and integrating dynamically by the finding and interacting with services in Web Services architecture. At the same time, the model extends the role of service requestor by utilizing business processing management, in order to realize the automatic business processing of the enterprises, which organizes Web Services provided by partners in the order of the real business processing procedure.Finally, illustrate how the SPIDE model implements dynamic information system integration between a travel agent and its suppliers or partners on Internet to do business via dynamic E-business systems against the travel agent's requirements. And this scene is an answer of solving information integration problems to China's travel industry.
