Databases Normalization Assignment

Using the INVOICE table structure shown below, do the following:

Table 1: Sample INVOICE Records

Table unable to paste into here, it is in the uploaded file.

1. 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.)

2. Remove all partial dependencies, draw the new dependency diagrams, and identify the normal forms for each table structure you created. (Hint: You can assume that any given product is supplied by a single vendor but a vendor can supply many products.)

3. Remove all transitive dependencies, and draw the new dependency diagrams. Also identify the normal forms for each table structure you created.

4. Draw the Crow’s Foot ERD.
