The integration exercise given in class was difficult. Lucky it was a group exercise, not sure anyone could do the whole thing by him/her self. Even in a group, we still wasn't able to complete the whole exercise. At the end of class, it is nice to get different views from each group on how they were going to integrate. Some were similar to our group while other was totally different. In my mind there are many ways to integrate databases, but its all come down to cost and time.
