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 and to adhere to the naming conventions. c. Using the results of Problem 4, draw the Crow's Foot ERD. Note: Although the completed student hours (STU_HOURS) do determine the student classification (STU_ClASS), this dependency is not as obvious as you might initially assume it to be. For example, a student is considered a junior if the student has completed between 61 and 90 credit hours.

Question

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 and to adhere to the naming conventions.

c. Using the results of Problem 4, draw the Crow's Foot ERD.



Note: Although the completed student hours (STU_HOURS) do determine the student classification (STU_ClASS), this dependency is not as obvious as you might initially assume it to be. For example, a student is considered a junior if the student has completed between 61 and 90 credit hours.
