DataSource in SAP BI/BW


è
è 
DataSources are used for extracting data from a source system and for transferring data into the BW. 
 
è
èDataSources make the source system data available on request to the BW in the form of the (if necessary, filtered and enhanced) extraction structure. 
 
è
èThe DataSources subdivide the data that is provided by a source system into self-contained business areas. 
 
è
èIn SAP source systems, the DataSources are assigned to applications, for example HR (Human Resources). The advantage here is that you are able to specifically access data evaluation for this application. 
 
è
èThe information required for the extraction process, that is, the BW-relevant properties of the DataSource, is replicated in the  BW by comparing metadata.
