Hi Madhusudhan,

BW is a Data Warehousing Concept, Whereas in DW they will use different tools for diffrent task like u might be hered about DW EX: Informatica,Cognos,Hyperien Sybase,Abinito etc.. But this are all different each one wehere as coming to SAP BW it's a SAP Product it Deals with all the tools with BW like Modeling, Extraction,Reporiting... and DW is Based on Star Schema and BW is Based On Extended Star Schema. Ex: if ur in a room u have so many chairs with in and some chairs are out side pulling chair with in the room would be easier rather than going for another room.. Assume that Tools are chairs and room is ur Concept(DW or BW).

I think It helps...Assign Points if it helps u...
