When I was studying Relational Database Concepts in college, there was a catchy mnemonic for 3NF: "The key, the whole key, and nothing but the key, so help me Codd."
It's a good catch phrase. Been around a long long time.
Did they tell you that:
1NF = The key
2NF = The whole key
3NF = Nothing but the key
?
