Is SAP HANA a Hybrid Database?

Hi all,

I'm currently trying to find a thesis question about SAP HANA!
From my understanding SAP HANA is a Hybrid database, having a Column-based store and a Row-based store.

Therefore, I thought we have a duplication of data in 2 (or more) different databases one being Column-based (Or mix) and a Row-based (Or different mix).

Then I found out about HYRISE (Rodent-store: http://ares.epic.hpi.uni-potsdam.de/apps/static/papers/hyrise_hybrid_engine.pdf),

how does HYRISE fit in SAP HANA?

Does SAP HANA follows some HYRISE principals?

Thank you guys in advance for the help!
