All Together Now

In the preceding chapters, we have looked in detail at five UML diagrams that enable us to describe different aspects of a system. In the examples given, we have seen that the diagrams each realize different views of a system. Therefore, the diagrams must be interpreted together as a whole, taking into account how they interact with one another, rather than each one being considered in isolation. They supplement each other by illustrating the system to be developed from different perspectives. In this chapter, we model three concrete examples from different application areas that show the interaction between the different diagrams.
