Questions tagged [anemic-domain-model]

A domain model is "anemic" if it has little or no behavior. A model that only contains things, parties and places with no activities, is considered anemic. For example, a model that has only a 'Car' and a 'Car Dealership' is anemic because there is no activity (behavior) in the model that joins the two. For example, a 'CarSale' or 'CarService' activity represents behavior that joins the two and makes the model useful. Contrast with an "anemic object".

Having a domain layer that is only getters and setters for data values to/from the database is not a good OO design. Read more here
