Question 4: Use Case Analysis (6 Marks) Create a set of use cases for the accompanying dentist office system: When new patients are seen for the first time, they complete a patient information form that asks for 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 the patient arrives for the appointment. Because appointments are often made far in advance, the receptionist usually mails a reminder postcard to each patient 2 weeks before the appointment. You need to complete the information at the top of the use case form and identify the steps and the data flows within the use cases
