Agreed, so the sole purpose of Encryption is to prevent the OS users be it system admins or un-authorized users from reading the data file by either copying it to a new location or by using some vi tool at the OS level? Can the DBA/Admins still use Hana Studio or the HDBSQL to read the data from the database even after the encryption? I think the data is not encrypted at the Block level, like value "TESTING" will not be stored as "&*&yhsgasyu1". So after encryption do the DBAs need to do anything special to access the data using Hana Studio or HDBSQL?
Thank You so much for your answers. I am trying to understand the unknowns that might hurt us back once we implement it.
