Extract, Load, Transform (ELT)

ELT (Extract, Load, Transform) is a data processing approach where data is first collected from various sources (Extract), then moved directly into a data storage system like a data warehouse (Load). Once stored, the data is processed and organized (Transform) within the warehouse to prepare it for analysis. Unlike traditional methods, ELT delays data transformation until after loading, allowing for greater flexibility, scalability, and faster access to raw data for complex queries and analytics within modern data platforms.
