Demonstration number: 9We perform knowledge discovery in software archives in order to detect refactorings on the level of classes and methods. Our REFVIS prototype finds these refactorings in CVS repositories and relates them to transactions and configurations. Additionally, REFVIS relates movements of methods to the class inheritance hierarchy of the analyzed project. REFVIS creates visualizations that show these refactorings in two different layouts: - the package layout groups the refactored classes according to the packages. - the class hierarchy layout shows the refactorings in the context of the project's class hierarchy. We use color coding to distinguish between different different kinds of refactorings. Moreover, our visualizations are interactive as - they can be zoomed, scrolled and filtered, - mouse-over-tooltips allow to examine details of the particular refactoring on demand.
