Heterogeneous System Integration Platform for Large Scale Business Group

Nowadays, large scale business groups are facing the problems of heterogeneous systems interoperation, among which legacy systems interface standardization, secure cross-domain access and flexibility are three major issues to be solved. Current academic solutions either lack of security consideration or remain as prototypes in laboratories. Industry practices usually tend to abandon all legacy systems to set up a whole solution. In the presented approach, however, a platform with the Service Access Agent (SAA) framework is offered, under which we realize secure cross-domain interoperation of Web services as well as SAA based service orchestration. Some realization details are also described to offer a whole picture.
