Domain layer

Domain layer

The domain layer is a software concept.It is one of the layers in a typical multilayered architecture for information systems.One of the best and most well-known sources of information about how to use a domain layer can be found in Eric Evans's book about Domain-driven design.

The domain model is a part of the domain layer. It is a software model with classes that represents actual concepts from the reality.These concepts are called Entities and Value objects in the terminology of Domain-driven design (DDD).There are some other DDD concepts that are not part of a domain model, e.g. Services and Repositories, but still part of the domain layer.

The Domain layer is also known as the Business layer.
