Database question from essay grader

Post by jordansalivan » Tue Jan 30, 2018 3:11 pm

Why in the table `forum_users` the field` id` int (11) unsigned NOT NULL AUTO_INCREMENT, if you do not use it? and vice versa, why in the table `forum_posted` the field` author` varchar (255) NOT NULL, is not a key?
