SARA Archive Administration
Since innovations through IoT (Internet of Things) or big data scenarios not only affect the SAP basis, but also highlight products and services for customers of their own company, the role of the SAP basis in relation to these scenarios and services must be clearly defined. In general, the SAP basis sees its responsibility here in the connectivity to the corporate network or the enterprise systems, which lie in the responsibility of the SAP basis. The support of the applications, based on the technologies as well as the associated services, is the responsibility of the respective department that offers this service. A SAP-based support service must be agreed and regulated during the conception.
The core of the three-layer model is the application layer. This consists of one or more application servers and a message server. Companies use the application server to provide services for the operation of applications in SAP. The message server serves as an "intermediary" between the applications and services, for example, by controlling communication between the individual application servers and determining the load on the application servers. Furthermore, the data is prepared for the user in the application view so that the user can call up the data visually in the presentation layer. At the same time, the user data is forwarded to the database.
MONITORING AND ADAPTATION OF STANDARDISATION
Application layer: The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer. Data that the user enters in the SAP GUI is passed on to the database via the application servers.
"Shortcut for SAP Systems" makes many tasks in the area of the SAP basis much easier.
The website "www.sap-corner.de" offers many useful information about SAP basis.
Even for companies that hand over operation of the SAP Basis to an external service provider, there are often tasks from the user and authorization management environment at this point.
