I can't imagine staging tables with the same layout as production
tables. By that I mean that generally speaking, inbound data isn't
typically normalised. Or free of decimal data errors (commas, decimal
points, minus signs and currency symbols in amounts, slashes or dashes
in dates, etc.) So in my case, I always use different names for the...
raw input as opposed to the final destination, production tables. I
keep them in the same library because they have similar security
requirements. If I don't want someone peeping at birth dates in
production, I probably don't want them peeping at them in a staging
table, no matter how transient that data may be.
