1. Use the Invoice table structure shown below to answer the following questions:
a) Draw the dependency diagram and identify the primary key and 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, re-draw the new dependency diagrams, and identify the normal form for the table structure you created.

d) Include the relational schema for the final database table structure. Identify all primary keys.
