ETL stands for extract, transform, and load, which is the process of retrieving data from a variety of sources, transforming it into a suitable format, and loading it into a data warehouse. Therefore, ETL is not a data source but a method used to transfer data into a data warehouse. ERP (Enterprise Resource Planning), Legacy (existing systems), and POS (Point of Sale) are all data sources that can provide data to a data warehouse.
