Database Design and Normal Forms

Database Design: coming up with a ‘good’ scheme is very important.
How do we characterize the “goodness” of a scheme?
If two or more alternative schemes are available how do we compare them?
What are the problems with “bad” scheme designs?

Normal Forms:
Each normal form specifies certain conditions
If the conditions are satisfied by the schema certain kind of problems are avoided
