Imagine a single poorly-designed table, r(R), with attributes A, B, C, D, E, F, G, H, I, J, K, L, M. You’ve looked over the naughty designer’s work and come up with the following logical functional dependencies. A —> {B, D, F}? B —> {G, H, I}? {A, C} —> {E, J, K}? {J, K} —> {L, M} H is a composite attribute group with 3 attributes; H1, H2, H3. H3 is a multivalued attribute. L is a multivalued attribute....

Using the STUDENT table structure shown in Table P6.4, do the following: a. Write the relational schema and draw its dependency diagram. Identify all dependencies, including all transitive dependencies. b. Write the relational schema and draw the dependency diagram to meet the 3NF requirements to the greatest practical extent possible. If you believe that practical considerations dictate using a 2NF structure, explain why your decision to retain 2NF is appropriate. If necessary, add or modify attributes to create appropriate determinants...
