What is SAP?
SAP is recognized as an
ERP software practiced for integrating and automating complex business
processes such as production planning, human resources management, inventory
management, customer service, distribution, finances or logistics. SAP
architecture is classified into three layers or servers. There is the
presentation layer, the application layer, and the database layer. Each of them
is capable of specific processes and presents to the good functioning of the
whole system. They all work on separate servers unlike the two layer
architecture, where the presentation layer and the application one were on the
same server and the database layer was maintained independently. Though, the
three layers architecture is usually utilized in production and in complex
systems. We can even talk about one level SAP architecture, in which all data
is stored on a single server.
SAP R/3 Architecture
When the client-server
technology turned famous between the ERP developers SAP released its SAP R/3,
in which, R means for real-time data processing and 3 means three-tier
architecture. Because of adoption of this technology that version of SAP ERP
was compatible with versatile platforms and operating systems. The newest
version of SAP ERP is SAP ECC 6.0 that is a replacement of R/3 architecture.
SAP has the business
precise 3-Layer Architecture and which is known as R/3 Architecture.It comprises of three 3
Layers:
1. Presentation Server/
Layer
2. Application Server/
Layer
3. Database Server/
Layer
1. Presentation Server/ Layer:
It is a customer for
every SAP Solutions. It is also known as SAPGUI. There are 3 types of SAP GUI
1. SAP GUI for windows-
Used on Windows OS
2. SAP GUI for JAVA-
Used on all OS where JAVA is supported
3. SAP GUI for HTML-
Used for web based
SAP gave various
versions of GUI (4.6c, 620, 640, 700, 710)
2. Application Server/ Layer:
It handles the client
request and processes them to the database. It contains dispatcher to process
and control the client request,
interpret the requests and , work process to process, Buffer areas to
cache the regularly accessed data. It consumes the pressure both from Client
and the server.
3. Database Server/ Layer/:
It is the region where
the complete data remains. It has its own queue, process, buffers, and request
handling device. Maximum databases are on Oracle. SAP is launching MAXDB
(without any license key), Microsoft SQL Server & IBM DB2 with reduced
charges.SAP is concentrating
SMB (Small Mid-sized Business) and developing SAP for almost 1 million/ Rs. 10
Lakhs/ per client.
Benefits SAP R/3 Architecture
SAP R/3 architecture
depends on its three layers which are an application server, database server
and presentation server, the application server is the third layer that was
added to the former two-tier architecture to make it three-tier architecture.
The presentation server of SAP R/3 acts as GUI and is an application known as
sapgui.exe. This application is placed on the client system which accepts the
input and forwards it to the application server that processes the requests and
returns back the results or the output of the input.
The advantage of this
architecture, aside from a number of users and speed, was the integration of
other modules with key and frequently used modules. The principal modules of
the organization were at the one place while all the actions within those
modules could be viewed in other related modules in real time. This also
immensely increased the production of recording and analytical tools and
management of various departments working at diverse places. Large companies
could install this ERP which would operate as an autonomous application for the
group and could also give the consolidated view of the whole industry at the
highest level in real time.
The cross application
functionality and enterprise-critical shared IT system supports in maintaining
business workflows even at the divisional level what makes application
remarkably user-friendly. It presents simple and comprehensive integration with
other successful non-SAP products. It can comply with various levels of IT
infrastructure in contradiction with SAP R/2 architecture that handled to run
on mainframe systems.
