Abstract:
This paper deals with modeling of Service-Oriented Architecture (SOA). SOA is an architectural style for analysis, design, maintaining and integration of enterprise applications that are based on services. Services are autonomous platform-independent entities that enable access to one or more capabilities, which are accessible by provided interfaces. The goal of SOA is to align business and IT architectures. Hence, a new designed service has to meet business requirements that are traditionally specified by a business process diagram. The approach, presented in this paper, helps to bridge the semantic gap between business requirements and IT architecture by using a method for transformation of business processes diagrams into services diagrams. In particular, the method deals with process realisation based on services and it describes choreographing of services towards fulfilling business goals.
