FlyAKite is a small company that sells specialty kites. Ina Cloud, the owner of the company, is very passionate about her business. She personally picks the 200 kites of different sizes and shapes that FlyAKite has in their inventory. They have several customers that order kites from them and FlyAKite needs to keep track of these orders. In particular, they need to know who ordered, when, how many kites of each type, and the delivery type (e.g., ground shipping, overnight). To increase profits, FlyAKite also wants to keep better track of their spending. They have several approved vendors for their products. They need to keep track of their purchase orders and the prices that different vendors charge for their products. Because FlyAKite is a small company, Ina herself oversees these purchase orders. A few times in the past, it turned out that the owner paid the same invoice twice make sure that the database tracks whether an invoice was paid or not so this doesnt happen again. Because of problems with losing and misplacing inventory, Ina wants the database to record which employee received the shipment from a vendor and which employee put it into inventory. That way she has a record that she can check. For kites in inventory, FlyAKite needs to keep track of the quantity on hand, quantity on order, current list price, model, size, and color. Models, sizes, and patterns are standard lists that need to be maintained separately.
