This question in not completely incorrect, but can be greatly improved. You should have re-formulated it:

"What are Wikipedia, Google, CodeProject and StackOverflow.com?"

If you asked and got good Answers, the Questions like your original one would not be needed!

Now, the answer is not that simple as you might think. It's absolutely impossible to explain in one short answer. It's rather a topic of quite a big article. Look by yourself:

http://en.wikipedia.org/wiki/Normalization_%28database%29[^].

Normal forms:
http://en.wikipedia.org/wiki/First_normal_form[^],
http://en.wikipedia.org/wiki/Second_normal_form[^],
http://en.wikipedia.org/wiki/Third_normal_form[^],
http://en.wikipedia.org/wiki/Fourth_normal_form[^],
http://en.wikipedia.org/wiki/Fifth_normal_form[^],
http://en.wikipedia.org/wiki/Sixth_normal_form[^].

Good amount of reading, isn't it it?
