Model-Driven and Pattern-Based Integration of Process-Driven SOA Models

Service-oriented architectures (SOA) are increasingly used in the context of business processes. However, the modeling approaches for process-driven SOAs do not yet sufficiently integrate the various kinds of models relevant for a process-driven SOA – ranging from process models to software architectural models to software design models. We propose to integrate process-driven SOA models via a model-driven software development approach that is based on proven practices documented as software patterns. We introduce pattern primitives as an intermediate abstraction to formally model the participants in the solutions that patterns convey. To enable model-driven development, we develop domain-specific modeling languages for each kind of process-driven SOA model - based on formal meta-models that are extended with the pattern primitives. The various process-driven SOA models are integrated in a model-driven tool chain via the meta-models. Our tool chain validates the process-driven SOA models with regard to the constraints given by the meta-models and primitives.
