The Chen ERD illustrates the relationship between the different entities in a bookstore system, including customer, admin, order, books, book category, and shop carts. The diagram shows that a customer can place an order by adding books to their shop cart, which is then saved in the system. The order is then processed by the admin, who manages the inventory and shipping of the books. The books are categorized based on their genre, author, or publisher, allowing customers to search and filter them accordingly. Each book has a unique identifier, which is used to track its availability and pricing. Additionally, the diagram shows that customers can have multiple shopping carts, allowing them to organize their purchases and place orders at different times. Using the Chen ERD, the bookstore system can effectively manage its inventory, process orders, and provide a seamless experience for its customers.
