I possibly could copy paste the entire factor as my answer however the link has all that's necessary including table good examples

Boyce Codd Normal Form is usually the most significant as well as the simplest to describe: Every non-trvial determinant is really a superkey (keep in mind "Arrows from superkeys"). The lesser normal forms are just worth mentioning because BCNF isn't dependency-protecting inside a couple of cases.

Good examples of BCNF and 5NF: http://www.dcs.warwick.ac.uk/~hugh/CS252/RDB-fundamentals-8-design-I.pdf http://www.dcs.warwick.ac.united kingdom/~hugh/CS252/RDB-basic principles-9-design-II.pdf

It is best to start here and browse about all the pointed out subjects:

It requires a little of your time to translate the terms using the concepts, but when you're worth your salt like a database designer, it will not take lengthy.
