This week we learned the ER modeling which we have only touched the surface in our CIS 301 long time ago. I find myself kind of slow figuring out the relationships among the different entity types, like minimun, maximum, foreign keys and etc. Especially when the graph gets more complicated and there are ternary relationship or rehearse relationship, I understand the concept but it just takes some time for me to interpret all the relationships and the symbols. From the long discussion we had during class, it seems that if the questions' wording are different then the answer might be different too.
Also, for the exercise we have done in class, a few of the given answer keys are different from the conclusion from our discussion. I think it would be better if they are consistent with each other, so there won't be any confusion when we try to redo the exercise by ourself after class or before the exam.
