I'm having table that i for cars reservation they enter first name,last name,etc..... the data that will be duplicated car model so i make another table that having all car models to insert it into reservation table, any user can reserve the same car model and only but the number that point to model in the reservation table what is the idea I'm sorry if that was silly question?
