zhoujian今天问起我database里面的normal form的问题，只是一年前学的东西，不能说全给回老师，但是毕竟没有记忆了（还有一点印象, poor）. I really don’t blame on my memory, I know I am not having an easy-forgetting brain. But again, it’s proved that I am not an academic guy. I read fast, comprehend quick, apply asap, and then move on, left most of memory behind me, and never had a chance to go back and pick them up. Sometimes, I just guess I could be way better to be an artist than an IT idiot. ai…life sucks, but I do love it.
