Default What is a KEY and INDEX
Can someone tell me what exactly a KEY and an INDEX is, relating to mySQL tables. I tried looking at mysql.com, but I'm just getting confused. I understand what a Primary Key is. It's the unique field in a table. But I'm not really sure on the subject...and why are they so important?

Any help will be greatly appreciated!
