Abstract

Distributed information systems are critical to the functioning of many businesses; designing them to be dependable is a challenging but important task. We report our experience in using formal methods to enhance processes and tools for development of business information software based on service-oriented architectures. In our work, which takes place in an industrial setting, we focus on the configuration of middleware, verifying application-level requirements in the presence of faults. In pilot studies provided by SAP, we used the Event-B formalism and the open RODIN tools platform to prove properties of models of business protocols and expose weaknesses of certain middleware configurations with respect to particular protocols. We then extended the approach to use models automatically generated from diagrammatic design tools, opening the possibility of seamless integration with current development environments. Increased automation in the verification process, through domain-specific models and theories, is a goal for future work.
