Rational Database Design
You are tasked to develop a database design for a retail company that involves shipping orders to customers. Order data includes an order date, a ship date, and one or more items on each order should be identified by a unique ID. The quantities of each item in the order, the order amount (total per item and per order), and the customer to whom the order is shipped should be added. Customer data includes a unique customer ID, customer name, and address. Items in the inventory have a unique item ID, description, and unit cost.

At the top of your Word file include the title of this Critical Thinking assignment, your name, and the date. The recommended readings this week include videos, tutorials and diagram components for creating a Visio ERD which will help you to complete this weeks Critical Thinking assignment.
