John,

Look, EVERY DBMS Server can be used "locally".

You install it on your own standalone computer,
You install your application that act as client,
And this works.

Yes, this looks to be LOCAL work. Correct.
But server run as separate process.


When we say "local work for Valentina" we mean usage of EMBEDDED Valentina
engine, when your APPLICATION have inside of self Valentina.
