Operational Reporting in S/4 HANA

Hi folks,

     I need a clear direction.

     In terms of reporting, what is the difference between SAP FIORI and HANA-Live ?

     Do we still activate HANA-Live when we are on S/4 HANA (Not Business Suite on HANA!) ?

     If yes, how then would we run these reports in HANA-Live ? Is there a reporting front-end for HANA-Live or will I access HANA-Live from FIORI ?

     Please help.

     Cheers,

     John
