Chapter 4, Problem 4.28PAE

For each of the following E-R diagrams from Chapter 2 C:

  1. Transform the diagram to a relational schema that shows referential integrity constraints (see Figure 4-5 for an example of such a schema).
  2. For each relation, diagram the functional dependencies (see Figure 4-23 for an example).
  3. If any of the relations are not in 3NF, transform them to 3NF.
