ETL (Extract, Transform, Load)

A data management process where raw data is extracted from different sources, transformed into a usable format, and loaded into a storage system for analysis and reporting.

Example

A financial institution might use ETL to combine data from different departments, such as loans, deposits, and investments, into a central data warehouse. The process extracts data from each department's systems, transforms it into a standard format, and loads it into the data warehouse, which makes analysis and reporting across the organization easier.
