【Abstract】 The application and information integration bottleneck of heterogeneous systems has been the great obstacle of the enterprise informatization process.In order to settle this problem,we build a semantic model of application integration that consists of three parts:semantic resource model,semantic computation model and their binding.Based on the semantic model,we introduce a platform-based application integration approach in which all application systems are published as services facing to the platform and semantic description of services and domain resource are built too.With the help of semantic information,the binding of service requester and supplier is built. Our approach makes application systems interchange with each other in a uniform mode and enhances their independency, flexibility and maintainability.更多还原
