ELT

Extract, load, transform: copying data from its source into a destination system as it is, and cleaning and reshaping it there afterward.

Because the raw copy is kept, a transformation can be corrected and run again without going back to the source. The same raw copy means uncleaned data sits in the destination, where it can be used by mistake.
