ABAP RESTful Programming Model

The ABAP RESTful Programming Model consists of three main layers:

• Data Modeling & Behavior
• Business Services Provisioning
• Service Consumption

The data modeling and behavior layer contains domain-specific business objects, that are defined with Core Data Services (CDS) and transactional behavior.

The business service provisioning layer consists of projection views with their projection behavior to focus on a particular aspect of the data model which is exposed as business services through the OData protocol.

The service consumption layer allows you to consume all types of OData services as well as OData Web APIs.
