Due to the changing scope of data management from centrally stored data towards the management of distributed and heterogeneous systems, the integration takes place on different levels. The lack of standards for information integration as well as application integration resulted in a large number of different integration models and proprietary solutions. With the aim of a high degree of portability and the reduction of development efforts, the model-driven development—following the Model-Driven Architecture (MDA)—is advantageous in this context as well. Hence, in the GCIP project (Generation of Complex Integration Processes), we focus on the model-driven generation and optimization of integration tasks using a process-based approach. In this paper, we contribute detailed generation aspects and finally discuss open issues and further challenges
