Connecting AO to HANA

Hello All,

I see a lot of posts how to connect AO for Microsoft to SAP HANA. Question arises is what is the preferred way of connection

Option 1 - ODBC driver

Option 2 - HTTP/HTTPS.

For Analysis for Olap I am using Olap Connection made in CMC. hope that is the preferred way.

Regards,

Vivek
