The growing need for the integrated usage of information from different sources has led to the requirement for information integration. This paper proposes a business-oriented SOA deployment approach, which is derived from a real world project, for the agencies of technology to provide value-added services through integrating the existing information resources. In the approach, information services, which are supposed to be identified in accordance with information category standard, are created and used in a resource-centric way, and the concept of business service is brought out for domain users to ease the usage of information services by modeling business context and IT information coherently. Based on business services, a domain-specific service mash-up language is provided to “program” information integration applications, and the corresponding run-time support is built to parse the applications and execute business services in mediation-style architecture. The system implementation and the application of our approach are also given.
