The Study of SOA/CBD-based Next-Generation Business System Platform Design

摘要

In the early stage, we had to design e-Business service system the way that makes process as to classify functions on the basis of functionality. However, as becoming expanding service and complicating functionality, design pattern has been changed into service point of view not function point of view. Also, technology trend became advanced with focus of service-oriented. Then SOA, the new technical concept, has been introduced and applied to e-Business system design. That is, it means it will be progressed with service-oriented top-down way not function-oriented top-down way when service system is defined. Therefore, this paper proposes the next-generation e-Business service platform that applies to SOA concept and is designed with CBD method. It firstly analyzes functions operating at legacy e-business service systems and redefines those functions with service point of view. And it groups into components unit and it reuse legacy application resources. To do this, it will be able to upgrade e-Business service system and to increase efficiency of resources as reusing legacy resources. Also, it is easy to migrate new service to e-Business system because of service engine. And legacy system's modification will be minimized because of reusing the legacy modules and providing interface adaptor.
