ELT (Extract, Load, Transform)

ELT (Extract, Load, Transform) is a data processing approach used in data management. It involves first extracting data from various sources, then loading that raw data into a central storage system, such as a data warehouse. Finally, the data is transformed—cleaned, organized, and structured—within the warehouse to enable analysis and reporting. This method allows for faster data availability, leveraging powerful processing capabilities of modern warehouses, and is particularly useful for handling large or complex data sets efficiently.
