Performance tuning
The core of SAP Basis is the application layer with one or more application servers and a message server. The message server is used for communication between the application servers and transmits jobs between them. The application layer communicates with the database layer on the one hand and the presentation layer on the other. The applications on the application server request the required data from the database, process it and prepare it for the user, who displays it in his Graphical User Interface (GUI) via the presentation layer. Conversely, the application server passes information that the user enters via the GUI on to the database.
Tasks such as the update of components, the insertion of security updates or monitoring should be further automated. It is recommended to use only one automation tool (SAP Solution Manager or SAP LVM). Custom solutions and scripts should not be used or replaced with standard tools if possible, because otherwise different script languages and script versions will have to be managed, resulting in a lot of maintenance. Standardised SAP scripts are welcome here. A useful definition of thresholds, for example on the basis of historical system behaviour, must also be defined for monitoring.
Support in setting up connectors and interfaces
Before SAP HANA was released, there was no SAP database - you had to install SAP ERP (or the application you were using) on a third-party database, such as Oracle or SQL Server. SAP developed the HANA database to fully leverage the power of SAP's next-generation S/4 software.
In addition to the database, the SAP system itself is installed. This installation is planned using a tool from SAP, the "Maintenance Planner", and then carried out using the SWPM (Software Provisioning Manager) and SUM (Software Update Manager) tools.
With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.
The presentation layer is the interface to the users.
The definition, organisational structure as well as the naming of the SAP basis is historically conditioned by previous SAP software versions and components.
