Supporting the Evolution of Model-Driven Service-Oriented Systems: A Case Study on QoS-Aware Process-Driven SOAs
Process-driven Service-Oriented Architectures (SOA) need to cope with constant changing requirements of various compliance requirements, such as Quality of Service (QoS) constraints within Service Level Agreements (SLA). To the best of the knowledge, only little evidence is available if and in how far process-driven SOAs deal with the evolution of the requirements. In this paper, they evaluate an incremental and model-driven development approach on the evolution of the requirements and the domain model in the context of an industrial case study. The case study focuses on advanced telecom services that need to be compliant to QoS constraints.
