Following the consensus opinion of all those who kindly answered my inquiry 
(Re: QGIS Farm Application), i have installed Spatialite and managed to export 
all the data from a layer to a .SQLITE file, and then view it from several 
different SQLite browsers, which confirms integrity of data & database 
structure. This already is a constructive step forward (thanks to all those who 
helped, too numerous already to mention :). 

Moreover, i have managed to create a database in LibreOffice based upon that 
.sqlite file (after (re)learning more than i really wanted to know about ODBC 
drivers!), which displays all the data as it should. This is another good step 
forward, because -tho the business of my farm is predicated on geo-located 
resources (e.g. a paddock on the ground) having certain attributes that are 
best defined in QGIS (e.g. perimeter, area, etc.)- i will still be working with 
that data in spreadsheets on a much more dynamic basis. 

However: When i try to edit those .sqlite files from QGIS in another tool, i'm 
running into an error message that varies slightly, depending on the editor i 
use (anything but OO at this point: ODBC is too much pain, until i get these 
other mechanics worked out), but the message is essentially this (from 
SQLiteStudio): 
      "Error while updating cell value; no such function: RTreeAlign".

Presuming that what i am trying to do is in fact possible*;  then i am left 
scratching my head as to why all these SQL tools are having this trouble, and 
where that problematic function is coming from. Does that error message suggest 
anything to you? 

* (Of course, if what i am trying to do with such round-trip editing is in fact 
not possible, i would sure appreciate if someone could let me know :)
