1.whether the hana is replacement for existing DB ( oracle,sybase etc...)?

or just they exract the data from DB and keep in it and reporting very quick performace?

we know that SAP Ecc R/3 is having the following layer

1. presentation layer

2. application layer

3. DB layer

in our case our ERP will have the Sybase as DB

If we buy HANA means it will fully replacement of my DB (Sybase) or they Extract data from Db

and keep it in it (RAM-in memory ) and we want further do data modelling ?

If your ERP is not ECC on HANA then yes, you will have to extract the data from DB into BW on HANA and then it will be in memory for reporting which will increase your performances.

You can find some good articles on the SCN or Google, this one is one of them:
