BASIS is a lot more sophisticated than simply Systems Administration. Associate enterprise has servers unfolding across the world, each server running completely different SAP systems, versions and modules. Problems ceaselessly occur in any technical layer of the SAP landscape and it’s up to SAP Basis support to keep the enterprise cloud, info and application healthy.
- Basis Directors install updates, monitor the system for errors and tweak SAP to be quicker and reliable.

SAP R/3 Architecture:
SAP R/3 is a 3-tier architecture consisting of 3 layers-
Presentation: In simple words, it’s a client-server architecture where ‘R’ signifies ‘Real-time system’ and the digit ‘3’ represents ‘3-Tier Architecture’.
- Distributed System– When you have your DB and CI hosted on two (physically/Logically) separate hosts.
- Central System – When you have your DB and CI hosted on the same host.
Users can access the SAP system in two ways:-
- Through SAP GUI
- Through Web browser
It is known as the front-end and put in the user’s laptop solely and not in the application/database servers. Front-end takes the user’s requests to information and application servers.
Application Servers: Application server is built to process business logic. This workload is distributed among multiple application servers. With multiple application servers, the user can get the output more quickly. The application server exists at a remote location as compared to the location of the user’s PC.
Database Server: Database server stores and retrieves data as per SQL queries generated by ABAP and applications. However, Database and Application may exist in the same or different physical locations.
