Let's say you have database as source like Oracle, sap, SAS,hyperspectral etc.
If that is the case, we need ODBC drivers {Not mandatory}. But you can use after installing the drivers
We can even create connections on the fly which design by qlik in the script.
Why ODBC driver needed, just to avoid generic error line connection not found, server is down
Where you need to configure the driver, it should be in the all nodes.
