Terrible advice. What happens if they put in 1/2 of the data they want
to update, then have to close because they get called away?
Or, if it updates on the fly like you suggest, they update one field and
the system crashes, the power goes out, the internet connection drops -
whatever.
Someone trying to enter a new address comes to mind. You want all of
the changes or none of the changes.
