Viewpoint for Maintaining UML Models against Application Changes

The urgency that characterizes many requests for evolution forces the system administrators/developers of directly adapting the system without passing through the adaptation of its design. This creates a gap between the design information and the system it describes. The existing design models provide a static and often outdated snapshot of the system unrespectful of the system changes. Software developers spend a lot of time on evolving the system and then on updating the design information according to the evolution of the system. To this respect, we present an approach to automatically keep the design information (UML diagrams in our case) updated when the system evolves. The UML diagrams are bound to the application and all the changes to it are reflected to the diagrams as well.
