Hi, (maybe i'm posting in the wrong section, but i didn't find any appropriate one)
i am in the making of an ER-model (Entity-realtion model), and I think i didn't make it right, so can anyone help me with it? or at least give me some link or w/E where i could learn how to make it right? (my problem is i am not sure whter i should make a new Entity for something, or it can be a just a attribute of an older entity...)
Thank you.
