Understanding functional dependencies is critical to understanding which fields belong in which tables, and to work through the normalization process.

Discuss how you determine if a field is functionally dependent on another field (hint - think about a table we have used or read about - what the primary key was and what other fields are in that table). Provide an example of a field that is functionally dependent on another field. Is it possible for one field to be dependent on the combination of two other fields?
