Migration of SAP DB systems (between different databases)
Data cleansing
Over time, the tasks associated with the base became more complex and time-consuming, so that only the consultants could handle them. A need arose to hire a person to deal only with Basis matters.
Database layer: All of a company's data is stored in the database, which is located on a database server. Application programs pull the data they need from the database. This data can consist of data tables, applications or system control tables. In addition, the database also takes new information from users and backs it up.
Patching
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.
In the SAP Basis area, it is necessary to make temporary changes to the security settings of clients and systems in the course of system updates. You can use the system changeability variable to specify whether changeability of cross-client data, such as programs or menus, and cross-client customizing is allowed.
