Let's please not split hairs or mince words (especially not mine).
I made no mention of any other cost besides the database technology.
In that respect it isn't "mostly true", it's 100% accurate. SQLite
*is free* (public domain or no). Valentina is *not* a free product. I
cannot use it without licensing the technology.

This is mostly true but not entirely correct. SQLite is public domain,
though many commercial products have been developed from it for use
with
solutions like Director,REALbasic and Revolution. Yet Valentina 2
remains
incredibly popular on those platforms for serious commercial
development,
since the cost is negligible given the cost of commercial projects.
If your programmers work for free, then I see more reason to
consider SQLite
as free. But if you check what it costs to get into Valentina,
you'll see
that it's a minute drop in the bucket compared to a project cost --
something to weigh vs the performance benefits. If it makes the
difference
of if you have to troubleshoot just once with SQLite, odds are you've
already saved the cost of Valentina right there.

SQlLite is really "LITE".
So nobody should expect miracles from it.
We have good news for Cocoa developers!
Justin Drury have provide a lots of help to Paradigma SoftWare to
force poring of Valentina Database to Cocoa.
Justin already 2 weeks use Valentina, and he have very impressive
results.
I hope that Justin will post few comments to this list. Justin?
In any case you can read Justin comment right here:

Why this is good news for Cocoa developers?
Because Valentina is tens and hundreds times of faster than SQlLite.
I think in about of week, we will ship public beta of Valentina for
Cocoa.
We have many questions to Cocoa developers and may be Apple.
For example I have see that CoreData support M : M links.
Valentina 2 introduce revolutionary feature in its Object-
Relational
model.
This is Links. Valentina 2 have Tables *and* Links. You can
use 3 kind
of links for now:
- Foreign Key
- ObjectPtr
- Binary Link.
Binary Link support M : M link between tables. So it is very
interesting to see how it is possible plug this feature
into Core Data
model. They both looks to be born to be married.
