Create a set of detail use-case descriptions for the dentist’s office system in exercise E.

Exercise E

Draw a use-case diagram and a set of activity diagrams for the following doctor’s 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’s file; the full information will be collected when the patient arrives for the appointment. Because appointments are often made far in advance, the receptionist usually mails a reminder postcard to each patient two weeks before the appointment.
