Source of data for 'Reports'

Question

Hi all, 
 Can anyone please help me with all the possible source of data for Reports ? 
 If am not wrong, Appian reports can be pull data from database using Database queries 
 and secondly the pull Process data as well. 
 
 Is there any other source also ? 
 
 Thanks, 
 Preji

Preji, 
 
You can pull data from database using QE/QR, from processes using queryAnalytics, from external system using web services/ expressions. In summary, if you have the data in Appian then you can generate any Appian reports/ charts on that data.
