    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

    ?
