Answer 1

We can understand functional dependency in a way that assume we have two attribute and one attribute in totally dependent on the other is called functional dependency.

Say take a real life example. We know that everybody has a social security number against the name of the person . Say Frank is a person and we want to know the social security number of this person but database will be unable to help out with this information because there may be many persons named frank but we can determine name of person against social security number so name of the person is totally functional dependent on Social security number.
