I have a system that I'm building that I need to store extra information within an association table. for example. many to many relationship between consultant and learner the association table should have [consultant_learner] id consultantid learnerid timestamp withdrawndate active is there a best practice for this? More or less I'm trying to get my head around having logic within that intersection table. Anyone have link they can provide? Is this possible?
