This. It's why games and other licensed applications still get 
cracked, despite the industry spending millions (billions?) on 
researching means to prevent it.

Or don't let your application contact the DB directly. Build a 
web service or whatever fancy name those things have these days, 
and let the web service connect to the DB. Your application then 
connects to the service using a method of authorization if your 
choosing.
