Data movement and transformation with ETL – Extraction, Transformation and Load – or ELT – Extraction, Load and Transforamtion – processes consists of programmatically extracting, transforming and loading data from one or more sources into a target structure.
ETL and ELT processes are a key part of any company’s data management strategy.
