A company is building an online store where customers can browse products, add them to their cart, and place orders. To design the database, they use an ER diagram. They use rectangles to represent entities like "Customer," "Product," and "Order," and lines to show relationships between them. They use diamonds to show many-to-many relationships, like "Customer" buying "Product." They also add attributes like "Name" and "Quantity" to entities. This helps to organize and retrieve data efficiently. How would you represent a situation where a customer can place multiple orders, but each order is for multiple products, in the ER diagram?
