ETL (Extract, Transform, Load)

A vital process in data management, akin to a master chef preparing a gourmet meal, where raw data is extracted from various sources, transformed into a more palatable form, and loaded into a suitable storage system to be served and savored.

Example

A financial institution might use ETL to consolidate 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 standardized format, and loads it into the data warehouse, enabling efficient analysis and reporting across the organization.
