Use the technique of normalization to validate the structure of your relational schema. Demonstrate that each of your relations is in third normal form (3NF) by displaying the functional dependencies between attributes in each relation. Note, if any of your relations are not in 3NF, this may indicate that your ER model is structurally incorrect or that you have introduced errors in the process of deriving relations from your model.
