                  diagram forms provided by the Unified Modeling Language
                  (UML). The running example we use is a small traffic
                  light system which we first formally describe in an
                  object specification language. Afterwards, central
                  aspects of the specification and the specified system are
                  visualized with UML constructs. As a conclusion, we
                  discuss a classification of the various UML diagram
                  forms.",
