Extract, transform and load (ETL) was considered the most effective way to load information into a data warehouse.

ELT allows the more brittle components of the ETL process to be outsourced and automated by shifting the “transformation” step to the end of the data pipeline. By automating the “extract” and “load” stages, Fivetran enables rapid deployment, easy maintenance, and agile decision-making.
