The overall R/3 system includes the following components:
The UPPER layer, the functional layer contains the different business application. The integration of all application depends upon basis system. Applications are developed in ABAP/4 Lang. (Advanced Business Application – the 4th generation language)
The R/3 basis software is the set of programs and tools, which interfaces with the operating, system, the underlying database, protocols and the presentation interface. This layer enables all the application to work exactly the same way no matter what operating system or database, the system is installed on. It is an independent layer and ensures the integration of all modules. Besides all these specific jobs, BASIS system also contains following components and thus provides more additional features.
• ABAP/4 development workbench, which in turn includes many features like repository, data dictionary, workbench organizer, which will be discussed in later part of the topics.
• ABAP/4 language, system administrative tools, all these components are used to control, tune the R/3 system.
• Spool system manages the formatting of data for printing and passing it to the host spool system.
• Mail system you can send and receive mail from the outside world (Internet).
• Communication interface to external system from R/3 system: Manages communication at the OS level (TCP/IP), at the database level & between applications too. (RFC, EDI, and ALE)
• Database interface – This component supports different Relational databases from different vendors. The main task of database interface is to convert the SQL request from the SAP development environment to the database’s own SQL environment.
• Background processing with this facility you can submit your program for background execution.
BASIS system contains the layered components that facilitate the development of client/server architecture.
