Realm Databases-- we actually expected more of an uptick
in these when they first were released.
It's an alternative to SQLite.
How you know you're dealing with realm--
first, you may see it in the file name.
So we see default.realm.
That's your first clue.
Otherwise, these four bytes, 54 2D 44 42,
that represents realm.
You can see, you can use your database viewers
to look at these.
The format's just slightly different.
