Support for Basis Projects
SAP Basis is structured as a classic three-tier model. It contains the following components: Database layer (relational database management system) / Application layer (application server and message server) / Presentation layer (graphical user interface).
Application layer: The application layer is the central component of the SAP ERP system and is therefore also referred to as the base system. All applications and calculations are executed here. The application layer communicates with both the database layer and the presentation layer. On the one hand, it requests data from the database layer, processes it and then passes it on to the presentation layer. On the other hand, data that is newly entered in the presentation layer is passed on to the database layer and stored there.
KEEP COMPLEXITY PER CAPITA EXPECTABLE
In order to meet the growing integration and coordination between internal IT departments and external service providers and suppliers, it is necessary to include a company-wide interface department in the IT organisation. The SAP basis can assume the coordination role and interface function in the environment of SAP products and technologies.
Planning ahead: Ideally, your SAP system administrator should make the necessary adjustments to your system landscape before end users are affected. This requires careful planning and anticipation of long-term trends.
