Dear Experts,
I have read few documents regarding Hana and I am confused?
Following is my understanding. Correct me if I am wrong in my understanding?
1. I believe Hana is a database(a different kind of data base with Software and hardware) which stores the data and is very fast.
This Hana Database comprises of both Drive and Ram. Hana's Drive is for storing the Data permanently and Hana's Ram is where the full data from Drive is transferred to Ram and in-memory calculation happens which is very fast.
2. I read that we can have 2 options,a Standalone Hana which reads data from SAP ERP and BW on Hana. Why do we need to have BW on Hana, we can just have Hana itself right, because even without BW its faster?
Please correct me if I am wrong.
Regards
Sam
