And I say no - it is not. Unless you are a programmer, that
understands the primary storage format.
Because that is not standadized in a way that end users
can pull data from it in a meaningfull way.

Be that as it may, but it is in the end about data openess (for the
end user) or not.

That depends on the model amongst many things.
But that is not the most interesting question.
That one is about data openess for end users.
Do they have to hire someone to get data into a report,
or can they do it themselves.

And end users are rarely programmers in this case, but
they do know SQL, or are sent to courses to learn it.
