Do You Have a Legacy System?

A lot of the patterns that we've got ar about coexisting with with legacy. So one patten we find very useful is actually almost to do a bit of archaeology sesit wel where does that data get into the legacy system in the first place? And when we find that out, maybe what we can do is going that the new system, instead of having to pull that out of legacy, could actually go to the source of the data. We've seen examples of where that's been extremely useful.
