Book Review: SAP HANA: Introduction vs Implementation of HANA

Hi,

I am BI developer and am thinking of getting into HANA. SAP has a book sale going on. I see there are 2 books on Hana.

I would like to check which one would be better. I am a technical developer who understanding the concepts but not too much at the database level.

Kindly recommend.
