What are the entities of a supermarket?

The entities of a supermarket typically include departments such as groceries, produce, dairy, meat, and bakery, as well as non-food sections like household items and personal care products. Key entities also encompass suppliers, customers, and employees, along with the physical infrastructure such as checkout counters, storage facilities, and parking areas. Additionally, supermarkets might have loyalty programs, promotional displays, and online shopping platforms as integral components of their operation.
