Hi Nagaraj,
to start off with this topic I recommend to make yourself familiar with the available documentation on help.sap.com.
Modeled views like Analytic Views and Calculation Views are anything but the same as SQL views.
In fact these are processing models for certain query types that can show some very different ("non-relational") behavior than plain SQL views.
To digg deeper into this, check SAP notes
- SAP note HANA Calculation Engine Instantiation Processhttps://service.sap.com/sap/support/notes/1764658
- SAP note Performance degradation for query on CalcView https://service.sap.com/sap/support/notes/1825549

Make sure to not miss out on the attached documents to the notes!
And, before you ask: yes, you do need to have a valid S-user to access the sap notes.
