NAV2013 - Licensing for reading data from WS/DB

Hey there,


I've searched long enough to be very frustrated as I cannot find the answer to my question.


I'm assigned with a task to build some sort of frontend editor for employee data from navision.

Now I know about licence multiplexing and that I cannot just use a Webservice to get my data from a central server to present to the user.

But how about accessing the Database directly to READ data and use a periodic report from NAV to get and save the data back to NAV? Does this need to be licensed?



Is there a way to legally access the WebService to write/update without using 200 licenses?



PS: sorry if there are spelling errors, not my native language :)
