The Doctor Appointment Booking System is a comprehensive platform designed to facilitate interactions between patients, doctors, and administrators. Patients use the mobile app to browse content, purchase discount coupons, book appointments with doctors, manage payments, and update their personal profiles. Doctors, on the other hand, utilize the web app to manage appointments, track patient information, update their professional profiles, and handle payment transactions. Administrators access the web portal to oversee the management of doctors, patients, discount coupons, content, and appointment bookings, with the ability to control system settings. This system ensures a streamlined and efficient healthcare experience for all users.
