On the thursday(week 6)'s class we have done an exercise about Use-cases and Statechart in one of the subtopic in chapter 4. From that session, we as the student of S.E get to know more futhter about use-case characteristics such as use-case consist of an actor(s), use-case(oval shape- represent as a process), and interaction(arrow ->/<-).
Figure 1 : Show the characteristics of Use-Case.
In conclusion, we find that the use-cases is much more different from DFD(data flow diagram) not just from entire physical looks but also from interior that is use-cases can hide its details while the DFD types can view/show the details.
