Spotting an unknown number of changes between two visualizations of a complex software
application is a challenging task and error-prone without tool support. However, people
are interested in spotting changes in software applications at one glance. They want to
track changes in situations where the application faces varied loads or during the evolution
of the software application.
ExplorViz visualizes the behavior of software systems based on runtime data. These
visualizations support program comprehension. However, currently it lacks the ability to
handle two models and the ability to compare two models of a software system. In this
thesis, we upgrade ExplorViz to the effect that it is able to merge two models of a software
application. For that reason, we extend ExplorViz by an integrated software architecture
comparison view that additionally provides highlighting of model elements based on their
state. This enables the user to see at a glance which elements have been added, deleted,
modified or remained unchanged between the two models.
Subsequently, we apply our software architecture comparison view to the web-based
financial application LB-Rating and furthermore, conduct a qualitative usability study with
professional software engineers. In this study the participants are asked to solve tasks and
to comment on the usability. The study reveals that minor changes in providing feedback
to the user will help to ease solving tasks that aim at comparing two models.
