Back to Glossary ETL/ELT Data integration patterns used to move and prepare data from source systems into analytics platforms. ETL (Extract, Transform, Load) applies transformations before loading data into a destination warehouse; ELT (Extract, Load, Transform) loads raw data first and transforms it within the target platform, a model favored by cloud-scale environments like Microsoft Fabric where compute is… Data integration patterns used to move and prepare data from source systems into analytics platforms. ETL (Extract, Transform, Load) applies transformations before loading data into a destination warehouse; ELT (Extract, Load, Transform) loads raw data first and transforms it within the target platform, a model favored by cloud-scale environments like Microsoft Fabric where compute is elastic. Both patterns are foundational to reliable data pipelines and analytics workflows.
