Someone told me "It's the address of an object". Is that wrong?
Not always.
A handle is a number, a ticket. Something to identify something later
in your application. Your application doesn't know normally what it is.
* On Mac OS X a handle can be often a pointer to a pointer to data.
This way old Mac OS versions had a way to move data in memory as only
the second pointer changes.
* On Windows it is often an index in a table with objects.
* Sometimes a handle is an object reference.
The good thing is: Your app does not care. So if from one OS Version
to the next the handle is no longer an object, but in index in a
table, your app won't notice and still work.

Indeed, and that's how I do it, I was just commenting on why a hosted
solution (and by hosted I mean a regular web hosting solution, not
specifically a database host) may impair a desktop app trying to connect
directly to a db.
Try running it by IP and you will probably go crazy. Many computers
can only connect through dynamic IP addresses. This makes remote
connections to mysql almost unvereable.
It is much simpler to create a php service app to be the data gateway.
Best Regards,
Giovanni

So to make that work, you must be hosting your own server, correct?
While I many be ignorant, I don't see why. If you find a place that
hosts MYSql DB for example, why would it not be doable?
BTW that is how many apps worked BEFORE most things moved to
browsers.

Most hosts only allow connections from the localhost for databases,
for
security. You can allow hosts by ip typically, but obviously that's
a pain
for an app.
