Architecture Overview

SAP Business Suite features an ABAP engine, which is used for transactional applications, and an XS Engine, which is used for analytical applications. Back-end application artifacts and application content are stored in the back-end database.

In addition, the UI apps are deployed on a central SAP ABAP NetWeaver server, which also contains the UI Service Add-on for the shell services and the Gateway Add-on for the OData enablement of the ABAP-based Suite system.

Fiori apps are created using HTML5 and SAPUI5. For some extensions, the underlying jQuery JS library may be used. All supported form factors and operating systems are supported with one development project and a single code line per user interface app.
