Pattern-based business-driven analysis and design of service architectures

Service architectures are an increasingly adopted architectural approach for solving the Enterprise Application Integration (EAI) problem originated by business process automation requirements. In previous work, we developed a methodological framework for the designing of service architectures for EAI. The framework is structured in a layered architecture called LABAS, and is distinguished by using architectural abstractions in different layers. This paper describes the pattern-based techniques used in LABAS for service identification, for transformation from business models to service architectures and for architecture modifications.
