ERD Diagram

This figure reflects my Entity and Relationship Diagram. Basically, this is a kind of cycle. This ERD was completely based on my e-commerce website service. In simple words, this image alludes to a customer who first needs a credit card, to make a purchase, and this same customer has attributes (Customer ID, Email, Adress), these same attributes allow him to order products that have their own attributes (Product ID, Price). These products are contained in the customer's shopping cart. Once the customer make orders, the order is processed by the e-commerce service, and then the products are forwarded for shipping.
