SAP began in 1972 and has evolved through several releases to become the world's largest enterprise software company, with its current release being SAP Business Suite 7. SAP provides integrated enterprise resource planning software modules that can be customized for any industry, with a multi-tier architecture separating the presentation, business logic and data layers. A typical SAP landscape includes separate clients for customization, quality assurance, and production to ensure changes are tested before being implemented in the live system.

6. SAP History
 5 EX-IBM Engineers founded SAP.
Dietmar Hopp, Klaus Tschira, Hans-Werner Hector, Hasso Plattner, and Claus
Wellenreuther
SAP was started in 1972 in Germany.
Initially there vision was : Standard application software for real-time data processing is
developed.
The first client of this company was the German branch of Imperial Chemical Industries

7. SAP History
SAP has issued several releases, such as SAP R/1, SAP R/2, and SAP
R/3.
The R in these releases stands for “Real-Time” data processing.
The 3 in the R/3 stands for “three-tier” client-server architecture.
The most current release of SAP is SAP Business Suite 7.

8. SAP R/1

9. SAP R/1
1-Tier Architecture is the simplest, single tier on single user, and is the
equivalent of running an application on a personal computer. All the
required component to run the application are located within it. User
interface, business logic, and data storage are all located on the same
machine. They are the easiest to design, but the least scalable. Because
they are not part of a network, they are useless for designing web
applications.

10. SAP R/2

11. SAP R/2
2-Tier Architectures supply a basic network between a client and a server. For example,
the basic web model is a 2-Tier Architecture. A web browser makes a request from a web
server, which then processes the request and returns the desired response, in this case,
web pages. This approach improves scalability and divides the user interface from the
data layers. However, it does not divide application layers so they can be utilized
separately. This makes them difficult to update and not specialized. The entire
application must be updated because layers aren’t separated.

12. SAP R/3

13. SAP R/3
3-Tier Architecture is most commonly used to build web applications. In
this model, the browser acts like a client, middleware or an application
server contains the business logic, and database servers handle data
functions. This approach separates business logic from display and data.So
the 3 layers commonly known as: Presentation Layer(PL/UI),Business Logic
Layer(BLL) & Data Access Layer(DAL).

15. SAP Modules
SAP Divided into two Area:
1. SAP Functional Module
2. SAP Technical Module

16. SAP Functional Module

Controlling (CO)
Materials Management (MM)
Sales and Distribution (SD)
Logistics Execution (LE)
Production Planning (PP)
Quality Management (QM)
Plant Maintenance (PM)
Project System (PS)
Human Resources (HR)

17. SAP Functional Module

18. SAP Technical Module
ABAP – Advance Business Application Programming
BASIS
BI – Business Information
BW – Business Warehouse
HANA – High performance analytic appliance

19. SAP Client
A client is a logical portion of an SAP R/3 physical database.
From a business standpoint, a client can be interpreted as a
logical group of companies.

20. SAP Client
All customizing (configuration) and development (ABAP) work
in SAP R/3 is performed in a client.
However, the data from both customizing and development
work may be stored within an individual client (client
dependent data) or among all clients (client independent data)
in the system.

21. SAP Landscape

22. SAP Landscape
CUSTOMIZING AND DEVELOPMENT CLIENT: The customizing and development client is required
for checking any configuration changes or ABAP Workbench developments for errors before they are
implemented in the production client. This is because if some wrong configurations are
implemented in the production client, then it can hamper day to day operations and even cause
loss of important data. This process is called unit testing.
QUALITY ASSURANCE CLIENT: All the modules in SAP are tightly integrated and interdependent.
When any changes are made to the configuration or to the ABAP code the cross module effect of
these changes needs to be checked extensively for errors. This process of carrying out cross module
testing is called integration testing and is carried out in the quality assurance client.
PRODUCTION CLIENT: The production client is where the actual business transactions are
recorded. Any changes in configuration must first be tested on the development and quality
assurance client to make sure they are free from errors and do not cause system instability. Once
these checks are done, the changes can be made in the actual production client.
