DESIGN THE ER DIAGRAM

You will need to create a design to support Products, Orders, Customers and Suppliers. In addition, the design needs to support multiple products per order. Support customer branching. Some customers are one company but have multiple locations. From a technical point of view, please incorporate a many to many relationship.
