Dynamic System Adaptation by Constraint Orchestration

For Paradigm models, evolution is just-in-time specified coordination conducted by a special reusable component McPal. Evolution can be treated consistently and on-the-fly through Paradigm’s constraint orchestration, also for originally unforeseen evolution. UML-like diagrams visually supplement such migration, as is illustrated for the case of a critical section solution evolving into a pipeline architecture. 1 Problem Situation Software systems are large and complex. However, more strikingly, software systems have a strong tendency to grow over time, both in size and complexity. In order to deal with size and complexity, software architectures are used. A software architecture provides a global description of an actually far more detailed software system by giving an overview in terms of components and links. Components are the main relevant parts, links are the relevant connections between them.
