What is SAP BW?

BW/BI is called data warehousing tool. BW  can pull the data from any sort of application. 
The connectivity's integrated with BW system are
ØRFC Connections (Remote Function call)
ØBAPI (Business app programming interface)
ØDB (Database connect) Ex: Oracle, Sy-Base, DB2
ØFlat file
ØALE ( App Linking Enabling)
ØIdoc ( Intermediate Documents)
ØSAPI (System app programming interface)
ØSOAP (Simple object access protocol)
ØEDI (Electronic data interchange/interface)
ØInformation Broadcasting (For Reporting)

 In BI we have 2 types of Data 1. Actual Data 2. Planning Data 

Note :- Mostly we do have this actual data, Depends on the business only this Planning data will be available.

Presentation Server: The systems which are used to retrieve the data or enter the data are called Presentation Server.
Application Server: The systems which are used for data manipulations. The Main core s/w of the business will be installed only in the application server. The calculations and validations done over here.
Database Sever: The place where the data is permanently stored.
Dataflow: The applications are accessed through the presentation server connecting  to the application server and the values passed by the presentation server will be calculated/validated against the business requirement and data is sent to the presentation server and the data is permanently stored in the data base server.
The application server and data base server are located in the client location.

The BW transformations would be the EDW transformations & propagati
