Abstract
The use case diagram allows us to describe the possible usage scenarios (use cases) that a system is developed for. It expresses what a system should do but does not address any realization details such as data structures, algorithms, etc. These details are covered by other diagrams such as the class diagram (see Chapter 4) or the interaction diagrams (see Chapter 6). The use case diagram also models which user of the system uses which functionality, i.e., it expresses who will actually work with the system to be built.
