a. List the normalized tables using the standard table notation (remember Chen and/or Crow’s foot)
– Tablename (Col1, Col2……Coln)
  Primary Key:
  Foreign Key:
b. Draw the dependency diagrams for each of the tables.( Hint: you should have no less than four tables)
c. Provide an E-R Diagram of the tables to be created

3. Using the CREATE TABLE command, create each of the normalized tables. Run a DESCRIBE command for each table.
– Include the PRIMARY KEY constraint for each table.
– Include the FOREIGN KEY constraint for each table to which it applies.
– Include the NOT NULL constraint for Student Name and Instructor Name.
– Include the CHECK constraint for the Grade to ensure it is one of the 5 acceptable values (A, B, C, D, or F).

4. Code INSERT commands to insert the data from the attached page into the tables you created in 2.
– Run ‘SELECT * FROM tablename;’ commands to check the contents of your tables.

5. Your submittal/output to hand in should include: ( with no less than ten pages)
– Question 1, part a.: Primary Key columns
– Question 1, part b.: Dependency Diagram
– Question 2, Part a.: List of normalized table descriptions
– Question 2, Part b.: Dependency diagrams for the normalized tables
