SAP Architecture

[d4xtian]

We know that SAP has an architecture Client / Server R/3

So i assume that:

- SAP Logon is Presentation server

- NetWeaver is in the Application Server (Which containt Business Suite, so SAP ERP)

- Modules (FICO; HR, SD,MM, ABAP...) are they part of Application Server ?

- AS ABAP is in the Application Layer right ?

- Database is the Database Layer

Thanks you in advance.

SAP is the name of the company, so I'd rather say that R/3 has a client/server architecture. 3 layers: presentation, application, database. SAP Logon and SAP GUI are software which can be classified as belonging to the presentation layer.

SAP NetWeaver is not software, it's more a marketing concept, a suite of software.

A "module" is the traditional way of classifying features. Not related to software layers.

AS = Application Server = part of the Application Layer.

A database is part of the Database Layer.

Well let me explain which i know..

• Primary goal of SAP Architecture provides a set of tightly coupled in major business application.
• The SAP System Architecture includes Presentation, Application, and Database layers.

It is 3 tier architecture. Its a client server architecture.

1. Presentation layer -> Provides graphical screen to user, the user will enter the data on the screen
2. Application layer -> Process data using application logic and also it communicates with both the layers
3. Database layer -> Stores the data in Hana database

3. Database layer -> Stores the data in a database.

HANA is not the only possibility.
