HMS is an application that provides all the room managing functionalities required to run a small scale hotel business. When we say all it mostly refers to the rooms booking system and its billing system.   Its a PHP project, so I have posted the source file along with the SQL file, and don't mind the simplicity of the app since this is my college project, not a fully fledged application. But you could improve it if you want, but do include me on thanks or credits, and do notify me if you have used my source.
