By Now, you should have some basic idea of what is SAP. The SAP application is an integrated enterprise resource planning (ERP) software manufactured by SAP AG that targets business software requirements of midsize and large organizations in all industries and sectors.

What actually does R/3 mean: R/3 is an integrated suite of applications designed to handle the data processing for large corporations. It was developed in Germany by the company named SAP (an acronym for Systems Applications and Products for data processing).
Within R/3 is a runtime environment and an integrated suite of application programs written in SAP’s 4GL-ABAP/4. These application programs are designed to meet the data processing needs of very large businesses. R/3 and its predecessor R/2 are particularly popular with the manufacturing sector.
The sole purpose of an R/3 system is to provide a suite of tightly integrated, large-scale business applications. A few of these can be seen at the top of the above Figure. For more detailed information about R/3 And Functional Areas of R/3 read my earlier post Functional Areas Of R/3 In SAP | SAP Modules.
R/3 comes prepackaged with the core business applications needed by most large corporations. These applications coexist in one homogenous environment. They are designed from the ground up to run using a single database and one (very large) set of tables. Current production database sizes range from 12 gigabytes to near 3 terabytes. Around 8,000 database tables are shipped with the standard delivery R/3 product.
