Build a 1-pg Entity Relationship Diagram that models the required tables and relationships using Microsoft^® Visio^®, Lucidchart, or another software tool of your choice. The table design and relationships must support the following functionality:

• Customers - Each customer is assigned a unique customer number but may have multiple locations to ship to. The sales team needs to be able to select the customer and the location for preparing sales orders.
• Inventory Table - The sales team will want to query the inventory to find diamonds that meet the following specifications of their customers:Cost - what SD has paid for the stone
• Price - what SD will sell the stone for
• Carat - weight
• Clarity - clarity scale for diamonds offered are IF, VVS1, VVS2, VS1, VS2*
• Cut - cut scale for diamonds offered are Excellent, Very Good, Good
• Color - color scale for diamond offered are D, E, F, G, H, I, J*
• Order Table - The sales team will want to make a sales order for existing customers and sell only diamonds that are in inventory. The DBMS must be designed such that customers can purchase multiple stones on one sales order.

*Diamond Scale Reference*

• Clarity:IF- Internally Flawless
• VVS1 - Very, very slightly included (pavilion)
• VVS2 - Very, very slightly included (crown)
• VS1 - Very slightly included (under 10X magnification)
• VS2 - Very slightly included (to the naked eye)
