Data warehouses host data replicated from many sources and are often the foundation of a data-driven organization’s analytics stack. For this reason, organizations require effective data consolidation tools to support data warehousing.

While a variety of data transportation technologies are available, ETL is the most common method of data integration (Extract Transfer Load).
