Yep, for most purposes that would be fine. In fact, you could cut it
down further, if the data-entry mode is pretty safe: have the program
start up in data-entry mode, and it has one menu item "Switch to admin
mode", which prompts for a password.

If you were to create a web application, you'd have to worry about the
same question of "is this person an admin or just data-entry". If you
were to do this as a single program that other programs script, you'd
have to worry about the same question. It's not complexity inherent in
the model of "database is king, and there are several applications";
it's complexity inherent in the original problem "we will have
separate admins and data-entry people".

Incidentally, there is another way you could lay it out: have two
separate programs, one of which is the d-e and the other is admins.
That could work out very nicely, if you have a specially cut-down and
simplified UI for d-e. It'd be like how some accounting packages have
a special Point-Of-Sale mode, which doesn't have permission to process
anything other than straight-forward sales, and which will use the
entire screen just for that. It's a useful feature even when you
completely trust the people involved; the simpler UI can allow
increased throughput. There's a lot of flexibility here, and
ultimately, you get exactly as much complexity as you write into your
system :)
