Building correct by construction SOA design patterns: Modeling and refinement

Abstract

Modeling SOA design patterns with a standard formal notation avoids misunderstanding by software architects and helps endow design methods with refinement approaches for mastering system architectures complexity. In this paper, we propose a formal architecture-centric approach that aims to model message-oriented SOA design patterns with the SoaML standard language. Pattern models are developed in a stepwise manner which are then automatically translated into Event-B specifications that can be proved using the Rodin theorem prover. These two steps are performed before undertaking the effective coding of a design pattern providing correct by construction solutions. Our approach is experimented through pattern examples. © 2013 Springer-Verlag.
