I hope you don't expect decent performance from your application, or that you have very few users. Establishing a database connection is a very expensive operation. Getting a new connection each time you need to access the database is a definite performance killer. You do not, by any chance, have a mainframe background? What you want is typical in mainframes - the end user's identity is used to access the database thus enabling the db admin to lock down the database based on users or their roles.
