Azure: What is ELT

  • Data ingestion/extract is about moving raw data from various sources into a central repository

  • data loading involves taking the transformed or processed data and loading it into the final storage destination for analysis and reporting.

Any data migration endeavor is incomplete without also moving the tooling that processes, transforms and loads the data into the warehouse.
