Template for Managing and ART COLLECTION database

There is a "Collections" template.   Look at how "movies" was implemented..  It has an image.. some fields.. and a link to the "artist" table for the director and actors..   I really do not know the Art business.. but I suspect you may also want a "Patron" table or something to track if an Art piece is on loan from a "Patron" .. and a Donation table to track potential $$$$ donations.   

As for as "tutorial" ..  There are a few YouTubes floating around about using Ninox.. could start there. 

Hope this helps.
