INVOICE table structure shown below, do the following:
a. Write the relational schema,
draw its dependency diagram and identify all dependencies, including all
partial and transitive dependencies. You can assume that the table does not
contain repeating groups and that any invoice number may reference more than
one product. (Hint: This table uses a composite primary key.)
b. Remove all partial
dependencies, draw the new dependency diagrams, and identify the normal forms
for each table structure you created.
c. Remove all transitive
dependencies, and draw the new dependency diagrams. Also identify the normal
forms for each table structure you created.
