What is the purpose of an activity diagram?
2. How do you create activity diagram?
3. Draw a set of activity diagrams for the following dentist office system. Whenever new
patients are seen for the first time, they complete a patient information form that asks
their name, address, phone number and brief medical history, which are stored in the
patient information file. When a patient calls to schedule a new appointment or change an
existing appointment, the receptionist checks the appointment file for an available time.
Once a good time is found for the patient, the appointment is scheduled. If the patient is a
new patient, an incomplete entry is made in the patient file; the full information will be
collected when they arrive for their appointment. Because appointments are often made
so far in advance, the receptionist usually mails a reminder postcard to each patient two
weeks before their appointment
