Extract, load and transform, or ELT, is a data integration process that moves data directly from source to destination for analysts to transform as needed.

When it comes to modern integration, the ETL or Extract, Transform, Load process serves as the backbone. Essentially, the ETL process works to efficiently migrate massive quantities of information or data into target data warehouses or data lakes. And with the ever-growing importance of data in business, handling and processing data efficiently is becoming far more important than ever.
