I think this is reasonable, but I have no idea how, or if, this should
be written into the licence.

You don’t have a relational database. The collection of Shapefiles
could still be considered a database.

The software used, or whether or not the work is held in what we might
normally consider a database is not relevant.
From the directive[1], article 1:
“2. For the purposes of this Directive, 'database` shall mean a
collection of independent works, data or other materials arranged in
a systematic or methodical way and individually accessible by
electronic or other means.”
I would say all of your examples are databases under this definition.
