You left out the part where it was not very illuminating either. Assuming one decides that forgoing the authentication system built into every dbms is a good idea in the first place, authentication lends itself to a simple predicate (using the computer programming definition) or similarly simple subroutine regardless.

Your argument is as valid as stating one should create a square root function to isolate the program from numerical methods or a distance function to isolate the program from your choice of square root function.

While I consider the separation of concerns a sound design principle, your argument leaves me uncertain as to what concerns you intend to separate. Received on Thu Jun 01 2006 - 18:26:20 CDT
