Explanation
In ETL, data is transformed by a separate engine, often using staging tables, before it is loaded into the destination, so the data arrives at the target already processed. Needing a target store powerful enough to transform data describes ELT, where transformation happens inside the target. ETL is often used precisely because source and target schemas differ, and the target does not have to be a relational database.
