Using the Home library relation above:

1. Draw a dependency diagram to show the functional dependencies that exist in this relation.

2. Decompose the Home Library relation into a set of 3NF relations.

3. Draw the Relational Schema for each of these 3NF relations and show the referential integrity constraints that apply.

Verified Expert

The student will understand the concept of functional dependency and the types of full functional dependency, transitive dependency and multi-valued dependency. How to apply the normalization process to recognize the different types of normal forms and how to convert the table into dependency graph and representation of the table.
