Functional dependency and normalization

Question

I am trying to find a great resource to study for functional dependency and normalization.

Anyone have any idea where should I look to? I am having difficulty different

Answer 1

What is Functional Dependency?

Functional Dependencies are fundamental to the process of Normalization Functional Dependency describes the relationship between attributes(columns) in a table. In other words, a dependency FD: X → Y means that the values of Y are determined by the values of X. Two tuples sharing the same values of X will necessarily have the same values of Y.

What is Database Normalization?

Database Normalization is a step wise formal process that allows us to decompose Database Tables in such a way that both Data Redundancy and Update Anomalies(see above for more info on update anomalies) are minimized.
