Re: business rules?

That is like trying to get good, quick and cheap at the same time. 2 out of
3 is about the best you can do.

Paul, that's a really good question, and one which really deserves its own
thread - or maybe a forum <grin>. Short answer is, generally speaking,
you really want to avoid hardcoded business rules precisely because they
do require programming changes when the business logic changes. At the
same time, there's a tradeoff between maintenance, performance and
flexibility. You can usually get two out of the three.

When I get some more time, maybe we can address some specific instances.
think of allocations (warehouses that are non-allocatable, locations that
should be sequenced, etc.) or pricing (this one can go off the charts).

Joe/All,

What key architecture/design elements or software capabilities would you

see in an IDEAL ERP application relative to business rules? From your
experience, do most business rule changes require code changes? Does
the language effect this? (RPG, PHP, Java)

Reason I ask is that I've been involved in several projects lately with

more to come where the business rules have to be extremely dynamic.
We've had some success externalizing rules to data driven files but I'd
like to learn from the community experiences in this area.

Thanks, Paul Holm

to have made the attempt!
