Sorry, but you are looking at this all wrong... (Score 1)

What you have here is an opportunity for you to win.... (Cool Hand Luke +/-) It seems to me that your CLIENT has a new REQUIREMENT and YOU and your BOSS have an opportunity to PROVIDE a SOLUTION for a very reasonable price! (unless the current contract says that they can do this already) So why not setup what your CLIENT WANTS in a way that they do not "mess up" with "your database"? By the way unless you personally paid for the collection of the data, IT AIN'T YOURS. If you want to test my point go to your boss and tell him/her that you are taking your data home, and see what look you get as your butt is dragged out the door.
