How S-A-P Originated ?

First of all S-A-P is Pronounced seperately with the Letters S , A, P thats why I have added hyphen.

S-A-P AG a German Company was formed by 5 IBM Engineers in 1970's and over a period of 20 years they worked on different aspects of ERP and Came out with S-A-P in the year 1992 with their version SAP R/2.

1992 - SAP R/2
1994 - SAP R/3

Differences in SAP R/2 and R/3 ?

SAP stands for System Application and Production in Data Processing.

R Stands for Realtime.

R/2 Stands for Two tier Architect.

R/3 Three tier Architect.

In a SAP R/2 Architect ,

1 Presentation Server--------Presentation Server--------Presentation Server
__________________________________________________________________________

2

Application Server

Database Server

SAP R/2 works only on Mainframe Systems.

Database can be supported from other systems if database is as same as the Database server.

For Eg If Sybase is Installed in Database Server than only Sybase Database can interact with Database Server in SAP R/2.


In a SAP R/3 Architect ,

SAP R/3 is a 3 Tier Architect
