5) The design called for mustard on the buns, so mustard was
added to the bread recipe. We have seen a migration from fairly
simplistic two-tier client/server applications that baked many
of the business rules and field edits into the application
instead of putting them on the breakfast table where all of the
developers could reach them as needed. While this does not seem
to have much of an impact when you write the first application,
and perhaps not when you write the second, by the time you
get to the fourth or fourteenth, you can really see the problem
arise. Each time business rule code is included into an application,
you risk having to go back and change each and every application
when the rules change. For those shops where the
business rules never change, you can disregard this problem.
