Please let me know if Im correct and if not what Im missing.



1NF -- all tuples are atomic


2NF -- design allows transitive dependency?



I have 3NF and BCNF in my book and I understand them.



I dont understand the definitions of 4NF and 5NF. I cant find an
english definition of them. The proof language is tough to follow. Can
someone help me out?



There is a 6th and 7th NF too right? Is that it?
