(4.4) Entity Relationship Diagram

This is an example of a Customer Invoice. Each customer of Gaming Evolution would have an individual invoice, which shows each purchase that a customer makes. The invoice displays information about the item purchased, where it was purchased, the price of the item, both with tax and no tax, and the customer that is being billed.

Entity Relationship Diagrams can be used to show specific information about customers, which would especially help Gaming Evolution when the company is trying to show customer individuality. Customers would intern appreciate that Gaming Evolution is taking the time to know which games that the customer specifies. Simply by using the Invoice, customers would be more satisfied and will have a greater want to come back to Gamer Evolution.
