CHANGE OF PERCEPTION
Due to the large number of different constellations of database and SAP software, the job as an SAP Basis administrator is very diverse and, in addition to the topics mentioned above, also includes the following:
Basis includes a client/server architecture and configuration, a relational database management system (DBMS), and a graphical user interface (GUI). In addition to interfaces between system elements, Basis includes a development environment for R/3 applications, a data directory, and user and system administration and monitoring tools.
Overall, the application layer is the link between the database layer on the one hand and the presentation layer on the other. Thus, the applications on the application layer request required data from the database in order to process it afterwards.
Very good IT knowledge - especially of SAP solutions
Presentation layer: The presentation layer is the interface to the users. With the help of SAP GUI, the data is graphically prepared here and made available to the user on the screen. Furthermore, the data newly collected here is passed on to the application programs of the application layer.
