1) What is SAP?

> SAP was started in 1972 by five former IBM employees in Germany. It stands for Systems, Applications and Products in Data Processing.

> SAP SE, a global software company, is one of the largest vendors of ERP and other enterprise applications.

> In 1973, SAP released R/1, a financial accounting system. R/1 ran on IBM servers and DOS, and it had a single-tier architecture in which presentation, applications and data were on one platform.

> In 1979, SAP released R/2, a mainframe system that provided real-time data processing across accounting, manufacturing, supply chain and human resources. R/2 used a two-tier architecture, where presentation was on one platform and applications and data were on another. R/2 helped power SAP's growth, 

> In 1992, SAP released R/3, which represented a switch from mainframe computing to the client-server model, and from a two-tier to a three-tier architecture, in which presentation, applications and data were housed separately. R/3 was a critical product for SAP that launched the company onto the world stage.

b) Functional Modules
c) Techno-Functional Modules

> SAP has nearly 25 modules, however all the 25 SAP modules are not applied. The most implemented modules are the most successful and has the highest job opportunities. Such vital SAP Modules utilized by numerous organizations are as follows,

a) Technical Modules 

i) SAP Basis
ii) SAP ABAP -Advanced Business Application Programming

iv) SAP NetWeaver Etc...

b) Main Functional SAP ERP Modules 

i) FICO (Finance & Controlling)  
ii) HR (Human Resource)  
iii) PP (Production Planning)  
iv) MM (Material Management)  
v) SD (Sales & Distribution)  
vi) PM (Plant Maintenance)  
vii) PS (Project System)  
viii) QM (Quality Management)  Etc..

c) Techno-Functional Modules

1. ABAP + HR  
2. ABAP + SD  
3. BIW (Business Information Warehouse) 

5) The Environments for SAP ERP

i) Supported Operating System for SAP 

The SAP business suites can be installed on the following platforms (Operating systems):

ii) Supported Database for SAP ERP

SAP is a back-end-free ERP system which co-operate with many database companies. That means companies have many choices.   The database is common for all modules and avoids duplication of maintaining  master records. For e.g. the customer records will be maintained in SD module like  customer code, customer type, Credit/payment terms, address etc. The same would  be used by the FI module while perusing the customer accounts or entering the receipt of payments. Similarly the sales manager can view the customer balances in the FI module for follow up with the customer. 

The following Database can be used in SAP software. The functionality/programming technique is same for all database system.

a) Oracle
