    Question normalization

    Is there any advantage to normalizing beyond third normal form? Why or why not?

    For most tables, when you get to 3rd normal form you are done. 4th and 5th normal form relate to composite keys.

    Here is a tutorial on the subject - it's fairly complex to try to address here.
