The aim of this project is to develop an online hotel reservation system, a case study of FORT ELLIS Hotels LTD Gwagwalada, Abuja which corrects the inefficiency of the current existing manual system, where all bookings and reservations and other management activities are done manually. For improving hotel business and providing scope for global reservation of rooms we developed an online hotel reservation system which is a web application. The major programming language that was used for this project is MYSQL for the database and PHP technology for the frontend which is the main interface of the system where customers and agents can book rooms from any location.
