**TLDR:** A modern approach in which data is loaded into the target platform first, and transformations are performed later inside the storage or compute layer.

<p>ELT became widespread with the rise of modern cloud data platforms. In this model, data is first loaded into the target environment in raw or semi-processed form, and transformations are then executed within the warehouse or lakehouse itself. Thanks to powerful compute layers, transformation logic can run directly inside the platform, increasing flexibility. ELT is particularly advantageous in environments with large-scale data, rapid iteration, and multiple downstream use cases.</p>
