- 12. Global Data Strategy, Ltd. 2020 www.globaldatastrategy.com Data Virtualization vs. ETL 12 Extract, Transform, Load (ETL) • Best when physical movement, integration and storage of the data is needed • Enterprise-grade efforts where business rule planning & enforcement is required. • Batch updates & processing (e.g. nightly, weekly, monthly) • Supports data transformation, cleansing, grouping, etc. The two solutions can complement each other in an organization – it doesn’t need to be an either/or. Data Virtualization (DV) • Best when it is difficult, time-consuming, or expensive to physically move data. • Rapid prototyping or flexible environment where frequent changes required. • Near real-time updates of data • Delegates queries, joins and aggregations to the source system and returns the rows. ETL
