ETL vs ELT: The Key Differences

Extract, transform, and load (ETL) and extract, load, and transform (ELT) are two data integration methods used to replicate data from multiple sources into a central repository. ETL has been the traditional method for this process, but recently ELT solutions have gained popularity and become the new standard in the industry. Both methods involve automating the data integration process to reduce manual effort and improve efficiency. However, ELT offers several advantages over ETL, including faster processing times, more flexibility and automations, better scalability, lower cost, easier maintenance, better data integrity and reliability. These advantages have made ELT solutions the new standard for companies looking to integrate data from multiple sources into a central repository.
