You can't explain the complex with simple.

Well, some examples will be simpler than others... :-)
I provided some for OP, but this, or the complexity, is not a real problem; I would say, the real problem is a kind of laziness...

As you probably have problems with basic Web search, I'll do it for you:
http://en.wikipedia.org/wiki/Fourth_normal_form[^],
http://en.wikipedia.org/wiki/Fifth_normal_form[^].

If you think need even simpler examples, don't rush to complain: it could be considered not only as the lack of search/reading skills, but also as laziness. :-)
