This ERD of Online Shopping Project is a method for a database designer to visually represent the entities, or data objects, created in the system. The ERD is created before beginning work on the database itself, allowing the designer to identify potential issues and clarify business requirements. They can also be made for an existing system to serve as documentation. An ERD entity has attributes and relationships to other commodities. Entities are represented as rectangles with their details listed inside the box, and relationships are defined as arrows or lines connecting the rectangles.
