1. Identify all the candidate keys of the relation, and then identify all the functional dependencies in the relation.

2. Examine the determinants of the functional dependencies. If any determinant is not a candidate key, the relation is not well formed. In this case: a. Place the columns of the functional dependency in a new relation of their own. b. Make the determinant of the functional dependency the primary key of the new relation. c. Leave a copy of the determinant as a foreign key in the original relation. d. Create a referential integrity constraint between the original relation and the new relation.

3. Repeat step 3 as many times as necessary until every determinant of every relation is a candidate key.
