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

Abstract

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.
