Definition
ELT (Extract, Load, Transform) is a process that extracts data, loads them into a target environment and performs transformations only after loading.
Human Explanation
Unlike ETL, data are stored first and transformed afterwards.
Why it Matters
ELT makes it possible to use the computing power of modern data platforms and work with complete, unprocessed datasets.
Conceptual Boundary
ELT does not replace ETL. Each model is appropriate for different solution architectures.
Practical Perspective
ELT is widely used in modern analytical platforms and cloud-based solutions.
