Build a Website

Dear All, I have a small project, its a car rental that in a simple way in php for a university student. The site is really simple, just register and book the cars. I have the php files and css and everything but i could not find the Database file, this is an old project i did it from 5 years. So i need someone to check the .php files and create the database. The code was working before but missing the databsae, so i don't need you to touch the code just the databse. for an exeprt it will needs max 30minutes
