This are few of the fundamental database questions which has always given me trouble. I have tried using google and wiki but I somehow I miss out on understanding the functionality rather than terminology.

If possible would really appreciate if someone can share more insights on this questions using some visual representative examples.

What is a key? A candidate key? A primary key? An alternate key? A foreign key?
What is an index and how does it help your database?
What are the data types available and when to use which ones?
