Constraints in conceptual modelling: outlining an approach to business-driven web service composition

摘要

With Service-Oriented Architectures (SOAs), companies are facing a paradigm shift towards services as the key unit of their enterprise architectures. An exploitation of the potential of SOA is up to the applicability of business models for a transformation into service compositions. However, several shortcomings prevent semi-formal models from being a suitable resource of an automated transformation process. Problems result from a multitude of modelling aims, objects and procedures. This paper provides a method for business-process-oriented SOA design. A modelling environment gives an overview of business requirements and allows appropriate assignment of services to the business functions at the same time.
