What is a good KISS description of Boyce-Codd normal form?

Question

What is a KISS (Keep it Simple, Stupid) way to remember what Boyce-Codd normal form is and how to take a unnormalized table and BCNF it?

Wikipedia\'s info: not terribly

Answer 1

The best informal answer I've read is that, in BCNF, every "arrow" in every functional dependency is an "arrow" out of a candidate key. I don't recall the source, but it was probably something Chris Date wrote.
