all the SAPgui components and application servers) that produce R/3 system. The software-oriented view specifies the different software components (i.e. What is Software Oriented View of R/3 system? The presentation components are responsible for the interaction between the R/3 System and the user. Workbench is itself written in ABAP and is fully integrated in the R/3 system. We can create, edit, test, and manage application developments using workbench. The ABAP Workbench is a complete development environment for applications in the ABAP language. The tasks of the kernel and basis services are - “running applications”, “user and process administration”, “database access”, “communication” and “system monitoring and administration”. However, some parts are also written in ABAP. The runtime environment is mainly written in C and C++. hardware, operating system, and database specific). The kernel and basis services is a runtime environment for all R/3 applications (i.e. The tasks of three logical components tasks of the R/3 Basis system are described below - Kernel and Basis Services – The above diagram explains how the R/3 basis system constructs a central platform within the R/3 System. The difference between “logical view” and 'hardware or software-based view” is, not all the above components assigned to a specific hardware or software unit. The below diagram represents the logical view of the R/3 system. The R/3 System can have different set of views in different prospects. In R/3, R stands for Real-time and 3 stands for 3-tier architecture. The R/3 system is the platform for all other applications in the R/3 System.
