Jürgen Walter: Automated Transformation of Descartes Modeling Language to Palladio Component Model

Benefits Transformation

Tooling can be reused
Improves understanding of differences
Flexibility to change

Benefits Automation

Automated transformation is faster, less error-prone and less expensive compared to manual

extraction

SLIDE 4

Project Overview

Tooling has to be developed for each formalism
Comparison challenging
Manual transformation error-prone and time consuming

Problem

Model transformation of DML to PCM

Idea

Reuse of existing PCM tooling for DML
Improved understanding of differences and similarities
Simplified change of formalism

Benefit

Implement a model-to-model transformation

Action
