Model-driven Development of Serviceoriented Business Application Systems

The industrial development of real-world business applications that are based on service-oriented architecture (SOA) is subject to technological and organizational requirements. The paper describes an approach that tackles these requirements by ideas from model-driven development (MDD). The approach consists of a metamodel accompanied by modeling guidelines, a governance process ensuring that these guidelines are kept, and a modeling tool to support model creation and governance process. The successful application of the presented approach during the development of SAP’s Business byDesign solution shows that the benefits of MDD in software industry lie beyond code generation and outweigh modeling effort.
