Exercise C in Chapter 4

Draw a use-case diagram and a set of activity diagrams for the process of buying glasses from the viewpoint of the patient. The first step is to see an eye doctor who will give you a prescription. Once you have a prescription, you go to an optical dispensary, where you select your frames and place the order for your glasses. Once the glasses have been made, you return to the store for a fitting and pay for the glasses.
