$\begin{array} { l l } \text { Purchase order number } & \text { Product number } \\\text { Purchase order date } & \text { Product description } \\\text { Vendor code } & \text { Quantity purchased } \\\text { Vendor name } & \text { Unit cost } \\\text { Vendor address } & \text { Total ordered } \\& \text { Total due }\end{array}$
PURCHASE ORDER
Purchase order number: P0156
Purchase order date:Oct 6, 2012

$\text { Thankyou for your order! }$

$\begin{array}{|l|l|l|l|l|}\hline &&\text { Unit }\\\text { Product No}&\text { Description }&\text {Price }&\text {Quantity }&\text {Total }\\\hline \text { F135 } & \text { Excel Book } & \$ 25.00 & 4 & \$ 100.00 \\\hline \text { G1456 } & \text { Using Access } & \$ 35.00 & 10 & \$ 350.00 \\\hline &\text { Visio for }\\\text { B3429 } & \text { Dummies } & \$ 45.00 & 5 & \$ 225.00 \\\hline & & & & \\\hline & & & & \\\hline & & & & \\\hline & & & & \\\hline \text { Total }&\quad\quad &\quad\quad & \quad\quad&\$675.00\\\hline\end{array}$ Using the SYSTEM OUTPUT approach, determine the tables needed and put them in third normal form. Be sure to identify primary, foreign, and/or composite (concatenated) keys as necessary. Primary keys and composite keys should be underlined, while foreign keys should be identified with an asterisk. LIST ALL TABLES FOR FIRST, SECOND and THIRD normal forms.
