A Model-Driven Development Approach for Service-Oriented Integration Scenarios

The establishment of IT-supported processes within organizations requires the integration of existing distributed legacy applications. Therefore, Web services can be generated as wrappers to flexibly integrate existing distributed legacy applications using a standardized interface. Existing approaches mostly focus on the technical issues of the integration using Web services and do not support the developer during the description of an integration processes. Thus, in this paper we introduce a development approach that supports the developer in describing an integration process and finally allows a model-driven transformation of the prior defined integration process into Web service interfaces and XML schema definitions. Our approach is exemplified by a scenario at the Karlsruhe Institute of Technology (KIT) that implements a process to visualize the study progress of a student.
