How do relationships work in an e-commerce UML diagram?
Relationships in this UML diagram show how different entities interact, such as a user "placing" an order or a cart "containing" products. Multiplicity notations, like 1 to many, indicate if a user can have multiple orders. These connections are crucial for database design, as they define foreign key constraints and the logic required for complex online shopping workflows.
