Big Data Buzzwords From A to Z


ETL

Extract, transform and load (ETL) software is used when moving data from one database, such as one supporting a banking application transaction processing system, to another, such as a data warehouse system used for business analytics. Data often needs to be reformatted and cleaned up when being transferred from one database to another.

The performance demands on ETL tools have increased as data volumes have grown exponentially and data processing speeds have accelerated.
