Service Component Architecture (SCA) provides a first class model for building systems using Service Oriented Architecture (SOA). But SCA only focus on functional level service components. Considering a business system includes not only functional level components but also user interface and data level components, this paper presents a unified service composition framework to support business level service composition. This framework covers 3-layer composition, including functional, data, and user interface level service composition. An intelligent service composer based on this unified service composition framework is developed to enable business level service composition by business people under some advanced technologies, including intelligent service components searching, automatic service compliance checking, and template-based service adaptation. An example is presented to illustrate how a business people create a business application by using the intelligent service composer.
