Project #4 CRC cards and Class diagram
ACTIVITY DIAGRAM
The following activity diagram depicts the process of buying eye glasses from the viewpoint of the patient. The first step is to see an eye doctor who determines if the patient needs glasses then gives the patient a prescription. The patient goes to a glasses store, where he selects the frame and places the order for the glasses. Once the glasses have been made, the patient returns to the store for a fitting and pays for the glasses.
