Extension of the SAP system landscape
ABAP®/ABAP® OO
SAP administrators can basically be found wherever SAP systems are used. These are now numerous industries and departments of companies. SAP systems can be found in accounting, costing, activity-based costing and controlling. In all these areas, they take care of the smooth functioning and development, thus helping the company to make internal processes more efficient and consequently save costs and resources.
This is where all the system's data resides. These are composed of the actual database and the DBMS, the "database management system". In earlier versions, the database here came from different manufacturers. For example, Microsoft SQL or Oracle. Since SAP HANA, a lot has changed for IT in this data layer. This is because the database comes from SAP itself and is automatically monitored by the system. There is more to this database layer than just the working data. Important elements such as the configuration tables and system data for control and application content are also stored here. This is the repository data used by applications.
SAP Basis service on the safe side
SAP Basis is responsible for the smooth operation of the SAP Basis system. The SAP Basis system is like an operating system for R/3 as well as S/4. Every operating system, such as Windows, provides an environment in which programs developed for that environment can run, such as MS Office. Likewise, the SAP Basis system provides an environment in which SAP programs can run. In any R/3 or S/4 system, there is a database server, such as HANA, where the database resides. It provides the necessary data to all other applications. The data here is not only data tables, but also applications, system control tables and user data.
Here, too, the requirements profile for SAP Basis experts has shifted: Database administration is simply part of the job today. The majority of SAP customers place the SAP HANA database in the hands of the Basis team for build and run operations.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
