The UML toolbox is very rich. It allows you to model every conceivable aspect of the system. Nevertheless, to my mind, graphical models are not always appropriate. But, on the other hand, most people like them and they often make a good impression, suggesting clarity. . . Postacademische Cursus Informatie Technologie vrije Universiteit amsterdam
