SAP General Overview

It is a client/server enterprise application software SAP -ECC is arranged into distinct functional modules. Most common are FICO, HR, MM, SD, PM, PP, QM, PS,Each Module handles specific business tasks on its own but are linked with each other.

SAP typically focuses on the best practice methodologies for driving its software processes
SAP is now gradually moving from standard client server architecture to a completely web-based architecture where every transaction can be run from just a browser. These new dimension products developed on the web standards based framework (NetWeaver) are all under new umbrella called mySAP

SAP Client System

The R/3 System is a client system. The client concept enables the joint operation, in one system, of several enterprises that are independent of each other in business terms. During each user session you can only access the data of the client selected during the logon.

Client is, in organizational terms, an independent unit in the R/3 System. Each client has its own data environment and therefore its own master data and transaction data, assigned user master records and charts of accounts, and specific customizing parameters.

SAP Architecture

SAP works on Three Tier Client-Server Architecture :
  • The Presentation Layer (User Terminal) 
    • where Data creation, modification & Retrieval takes place. Collects user input and creates process requests 
  • The Application layer (Application Server)
    • Managing User Requests. It uses the application logic of SAP programs to collect and process the requests 
  • The Database Layer (Database Server) 
    • Data Storage. It Stores and retrieves all data

Client / Server Detail

The three set of client / server :
  1. Development Server/Client : 
    • where all the development, customization and configuration is being done. If ok, the request is moved to Quality Server.
  2. Quality Server/Client : 
    •  All the testing (UAT) is being done I this server. UAT if ok, the request is transported to PROD Server.
  3. Production Server/Client : 
    •  Runtime activity is being done
