Abstract

ETL is short for Extract-Transform-Load. The ETL process extracts data from operational source systems, transforms the data, and loads the data into a target. The transformations to perform on the data can involve a plethora of different activities, e.g., filtering, normalization or de-normalization to a desired form, joins, conversion, and cleansing to remove bad or dirty
data. In the ELT variant, the data is extracted from the source systems, loaded in its raw form into the target, and then transformed.
