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. date: 2008-12-15 date_type: submitted publisher: Newcastle University place_of_pub: Newcastle University TR, accepted to appear in Proceedings of ICECCS 2009 official_url: http://www.cs.ncl.ac.uk/publications/techreports/trs/papers/1131.pdf citation: Bryans, Jeremy W. and Fitzgerald, John S. and Alexander, Romanovsky and Andreas, Roth (2008) Formal Modelling and Analysis of Business Information Applications with Fault Tolerant Middleware.
