I am trying to learn how to Normalize databases. I understand the initial concept but am having a lot of trouble figuring out dependencies. For instance I have this table that had some blank attributes and I have filled them in to make it 1NF I think. But Im not sure what comes next. It seems to me that this table can be broke into three tables and it will be in 3NF as PAT_NUM>RM_NUM , ORDER>COST , PHYSICIAN>OFF_NUM. They seemed to be the only dependents in this table. Am I on the right track?
Thanks for any help.
