I can normalize upto the 3rd normalization form but I need some help on the 4th and 5th. Can anyone assist me?

In my experience I've never found a need to go beyond 3rd.

4th and 5th should be relegated to information theory classes.

Actually I came across a project a little while ago, where the database system of the Star Trek universe was simulated (don't ask why (-: ). And we did come across 4NF and BCNF.

I must admit I have never seen a 5NF example, to date, yet. :)
