This document discusses the aims and objectives of a hospital management system project. The project aims to create a doctor-patient interaction system using web and mobile applications to improve communication and allow for online booking of appointments. The proposed system uses public key encryption like AES to securely share information between doctors and patients. It allows patients to register, find doctors by specialty, book appointments, and view doctor profiles. Doctors can view patient complaints, post solutions, and manage their schedules. The system aims to streamline the appointment booking process and save time for both patients and doctors.
