SAP HANA Smart Data Access

Hi ,

I created smart Data Access setup with Sybase IQ in  SAP HANA , all working fine .

Now , I  have following questions

Let us assume the following :

userA                             -->Remote source owner

userB                             -->  Have permission to create vitual tables and use virtual tables created by UserA.

DataSource                        --> Sybase

virtual table  created by A       --> vtableA

virtual table  created by B       --> vtableB

Sybase IQ user  --> iquser

From my point of view HANA user is typical application user , that creates ODBC connection to  remote source coonected to HANA

to my knowledge this is the workflow of the SDA

          1.  From which user HANA creates ODBC connection with Sybase IQ  when  UserA executes queries in vtableA

          2.. From which user HANA creates ODBC connection with Sybase IQ when UserB executes queries in vtableA

          3.  From which user HANA creates ODBC connection with Sybase IQ when  UserA executes queries in vtableB

          4.  From which user HANA creates ODBC connection with Sybase IQ when UserB executes queries in vtable B

          5.  Is there trace  file that track  ODBC connections in SAP HANA ?

          6.  Is there any recommended way to Manage SDA from security perspective ?

Please correct me in case if my assumtions are wrong !

Thanks,

Razal
