Generic Ressources via Easy Connect are not that... easy... it's very consulting and programing intensive. You have to have a lot of knowledge of what to do (see the manual linked in the License overview of the ARM Configuration UI) and the target system so you can configure the CSV to be correctly interpreted.

SQL itself is a bit easier, but just a working "proof of concept". The package contains scripts that can be used to get the basic account informations. Follow the instructions on page 29 and you should end up with something similar to this:

And you have to know how to build a SQL connection string.
