One of the reasons this idea was suggested was because my client is
concerned that its "crazy" to be modifying business data in a system
that is running and processing purchase transactions. And I'm
wondering whether or not this is even a concern when most people build
this type of application. I think its going to be painful to keep
track of changes between the two databases (or schemas if you prefer).
It sounds like this would be highly prone to errors and cause more
problems than it solves.
Thoughts?
