Cooperation with internal support
In addition to the database, the SAP system itself is installed. This installation is planned using a tool from SAP, the "Maintenance Planner", and then carried out using the SWPM (Software Provisioning Manager) and SUM (Software Update Manager) tools.
As a hint: The menu tab "Jump" allows you to set all namespaces or software components simultaneously to "modifiable" or "non-modifiable". However, before you can rearrange the namespace and software components, you must also adjust the global setting accordingly. With Save or CTRL+S you can now save your new settings and you have already set the system modifiability.
Installation Services in all common environments
For example, many customer ABAP programs work by uploading or downloading data. There are potentially large security gaps here that allow access to server data. In addition, the widespread direct invocation of operating system commands that are not covered by a self-programmed authorization check is a major problem. Even though classic SQL injection, i.e., the entry of extended SQL commands, is a potential security vulnerability, it occurs rather rarely in SAP systems. More widespread is the unintentional dynamization of SQL calls because input parameters are not sufficiently checked. The need to check all in-house developments internally for such security vulnerabilities before they are delivered in SAP's own code has led to the development of the SAP Code Vulnerability Analyzer tool.
We can say that Basis is the operating system for SAP applications and ABAP. Basis provides services such as communication with the operating system, database communication, memory management, application data collection at runtime, web requests, business data exchange, etc.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
Basis operation is the prerequisite for ensuring that the SAP system is fully operational and covers the business processes well.
With SAP HANA, you can achieve huge performance increases over traditional databases that were previously unthinkable.
