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 processdriven SOA -ranging from process models to software architectural models to software design models. We propose to integrate process-driven SOA models via a modeldriven software development approach that is based on proven practices documented as software patterns. We introduce pattern primitives as an intermediate abstraction to precisely 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 meta-models that are extended with the pattern primitives. The various process-driven SOA models are integrated in a modeldriven 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.

Service-Oriented Computing: State of the Art and Research Challenges

“…SOA-based applications require a service-oriented engineering methodology 16 that enables modeling the business environment, including key performance indicators of business goals and objectives; translates the model into service design; deploys the service system; and tests and manages the deployment.…”

Formalizing "Traceability' for Architectural Evolutions

“…The patterns in this domain encode reusable design solutions that architects can use to model SOAs. A similar approach was earlier demonstrated by Zdun and Dustdar [10], who used pattern primitives as an intermediate abstraction to formally model the solutions. Likewise, other researchers have used patterns for composing enterprise architectures [11], and pattern detection using similarity scoring [12] to model architectures.…”

A model-driven approach to weave architectural styles into service-oriented architectures

“…From the methodological research point of view, there exist several initiatives for the definition of development process that follow a model-driven approach for building service-oriented solutions [4] [36], but none of them consider the architectural model as the key element during the development process. Additionally, those proposals do not consider the application of architectural styles as part of their proposals.…”
