what does ELT stand for? It’s Extract, Load, Transform.
ETL transforms data *before* loading, but ELT does it *after*. Why? Because modern data warehouses (like BigQuery) can handle heavy transformations on the fly.
ELT is more flexible—you can tweak transformations later without re-ingesting data. Tools like Talend or Matillion support both, but ELT’s the future tbh.
