The resource access layer is the layer between the business layer and a database or external services. The data access logic is responsible for persisting business entities to a database and retrieving individual business entities or sets of business entities on behalf of the business layer. The resource access layer may also contain service agents which are responsible for contacting other services to retrieve resources. The resource access layer should encapsulate all the code that deals with external resources (such as databases or other services), without leaking any of these implementation details to higher layers.
