SAP Basis Introduction and R3 Architecture Overview (in English)
NEW TECHNOLOGIES & INNOVATION
Maintaining the availability of critical business processes not only requires a high-quality infrastructure, but also places equally high demands on the management and operation of the underlying SAP NetWeaver and SAP HANA platforms due to their high complexity. These platforms are often referred to as SAP Basis.
SAP Basis ensures smooth operation of the SAP Basis system. The SAP Basis system is a kind of operating system of the R/3 system or SAP ERP. It includes three layers: database, application and presentation. In addition, Basis includes many SAP middleware programs and administration tools. With Basis SAP applications can be used compatible and independent of operating system and database and can be enriched with the necessary data.

The application layer is the central component of the SAP R/3 system. This layer is therefore also referred to by SAP as the actual base system. Within the layer there are application servers and a message server.
This enhances the capabilities of SAP HANA base administrators and increases the level of service they should provide. Your Basis team can more easily fine-tune your data replication strategy to meet demanding disaster recovery and high availability standards.
