Imagine you are employed as a database developer consultant for a hospital. They are currently in the process of developing a new database system which they require for storing information on their patients, doctors, medical records (past appointments, diagnoses, medicines, medicine prescribed date, allergies), appointments, and departments. Client Requirements When a patient wants to register to the GP in the hospital, they need to provide their full name, address, date of birth and insurance. Also, they must create the username and password to allow them to sign into the patient portal. The system will store the patient’s data. Optionally, they can also provide an email address and telephone number. The patients will then book an appointment through patient’s portal. System checks doctor’s availability. Appointment details are stored, including date, time, department, status (pending, cancelled, or completed) and doctor. When the patient arrives for the appointment, the doctors should check and review patient's medical record including past appointments, diagnoses, medicines, allergies. Doctor updates medical record with new diagnoses, and medicines. When a patient finishes his appointment and has seen the doctor, their status must be changed to completed and they can write a review/feedback for the doctor. If the patient has cancelled the appointment, he/she must rebook the appointment again. If the patient leaves the hospital system, the hospital wants to retain their information on the system, but they should keep a record of the date the patient left.
