Behavioral analysis of service oriented systems using event-B

Abstract

Service Oriented Architecture (SOA) is a widely used architectural style for constructing Service Oriented Systems (SOS). SOS incorporates several crucial features such as, service composition, service discovery; those are related with different behavioral aspects of SOS. Further, effective analysis of these behavioral characteristics depends on suitable specification of events and constraints in SOA. Thus, to achieve precise and correct specification for SOS, there is a serious need of formal conceptualization of SOA and its associated behavioral characteristics. In this context, this paper proposes a conceptual model for SOA using set theoretic approach and its behavioral aspects using Event-B language [2]. Further, correctness of the model is proved through Rodin platform [2]. A case study is also specified for exhibiting the practical usability of the proposed concepts. The novelty of the proposed work is to model SOA, its behavioral characteristics, related phenomenon and constraints in a way that is more feasible, effective and suitable for service-oriented system.
