ETL (Extract, Transform, Load)

What does ETL mean?

ETL is a data integration process in which data is extracted from various sources (Extract), transformed into a suitable format (Transform) and loaded into a target system such as a data warehouse (Load). ETL is an essential step for data-driven companies as it creates the basis for reports, analyses and business intelligence applications.

Advantages and areas of application

ETL enables companies to consolidate heterogeneous data sources and create a standardized database. This process improves data quality and ensures that analyses are based on reliable information. ETL is often used in finance departments, marketing teams and supply chain management to make informed decisions and optimize operational processes.
