SAP General Overview
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
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 Package is strategically divided into 2 main areas
- Functional & Technical
- People with domain experience can work on functional modules
- Two technical Modules are ABAP/4 & Basis
- In functional areas there are around 64 modules and all are enabled for web reporting via Web Application Server

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 :
- Development Server/Client :
- where all the development, customization and configuration is being done. If ok, the request is moved to Quality Server.
- Quality Server/Client :
- All the testing (UAT) is being done I this server. UAT if ok, the request is transported to PROD Server.
- Production Server/Client :
- Runtime activity is being done
