C) Submit the 3NF table(s) (use the shorthand table notation found on page 34, and 162). The tables and fields on those pages are similar to those assignment. That is because they are also based on Premier Products example. The main point in referencing those pages and tables is to provide examples of the notation format there may be similarities in content but base your submission on fields in the exercise. (15%)

Include a statement, in your own words that explains the primary key selection: why is that field a good choice for the primary key? (10%)<o:p>
