ER Modeling is making more sense to me as the classes go on. I don't mind doing the exercises as they are sort of like logic puzzles which I have always liked. The one thing that bothers me is in ER exercise #3 when we were getting different answers in class than the print-out had written. It seems that they were always going from top to bottom, which is what I was tending to do also, but in class we were often going from bottom to top. I don't understand how the ER model can be accurate if you can get different logically correct answers from the same diagram. Is one way more right than the other? For example, in number 9 is the documented answer really wrong?
