Hello I'm making a website for my school and I'm using myphpadmin and php. I wanted to figure out how to how to setup tables for a professor review system. Each name is going to has the attributes [department,rating,easiness,textbook,time stamp,course,curve,comment]but professors are going to have multiple columns because its a review system where you could add a review for the professors with said attributes. I wanted to be able to sort by alphabetical order and sort by department, how many tables should I have? Which should be the primary keys?
