SAP Basis - the secure foundation of the SAP system
As we know, BASIS is a set of tools. This tool has the following different functionalities.
The database layer is used to store all company data and consists of the database management system (DBMS) and the data itself. In every NetWeaver system there is a database server on which the SAP database is located. It provides all other applications with the necessary data. The data is not only data tables, but also applications, system control tables and user data. All basic components ensure that the user has fast and reliable access to this data.
SAP Basis in the overall system
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.
The core component of SAP Basis is the application layer. It contains one or more application servers and a message server.
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
Each operating system provides an environment in which programs can run, such as MS Office on Microsoft Windows.
There are very few differences between permissions.
