4+1 Views for a Business Cooperation Framework Based on SOA

Abstract — The paper analyzes LD-CAST, a business cooperation framework for automated or semi-automated business services, realized by various processes that orchestrate late bound Web services. The 4+1 Views Architecture proves to be appropriate for the analysis and design of systems with complex objectives, like: user friendliness for multiple actors; maintainability and extensibility under business evolution conditions; flexibility for dynamic retrieval of service providers; performance traceability for software and users. The paper presents the correspondences established between use-case, process, logical, implementation and deployment views, such as to attain these objectives, and to hide the back-stage complexity for the business domain users. The solution is based on three pillars: Service Oriented Architecture (SOA), Business Process Modeling (BPM) and semantic Web. The three of them are also used for comparing our system with other similar works
