Netezza vs. HANA

Hello together,

I've heard from a supporter of IBM that Netezza is cheaper and better than SAP HANA. I'm not really sure what I should think about this. So I want to ask you:

- Has someone of you a few facts for me regarding the differences between IBM Netezza and SAP HANA?

- Is the main architecture of the current available versions similar?

- I think the SAP BW integration is much better with SAP HANA. But has someone of you any information regarding the SAP BW integration of Netezza?

Regards, Alex
