You’ve worked with ABAP, SAP Fiori, and core data services—now see how these technologies and more come together in the ABAP RESTful application programming model. Learn to develop applications optimized for SAP S/4HANA, whether your system is on-premise or in the cloud.

The ABAP RESTful application programming model is a new way to develop enterprise applications on the ABAP platform. The programming model includes all application development steps and elements: the data model; operations (e.g., creating, reading, changing, or deleting business objects); business logic (e.g., calculations or checks); transactional behavior (e.g., locking behavior, numbering, etc.); and technical interface (typically, OData).

REST architecture
Core data services (CDS)
Behavior definition and implementation
