I've had to develop a system like this before. We were a data centric, mostly SQL shop. The idea was that the BA, CEO, and other devs could all implement the system for different customers having slightly but sufficiently different business rules. This is how we did it. Thankfully it was rewritten and the few customers migrated to the new system before it had a chance to fall on its face. -edit- "Make it Data-Driven" was the word.
