Today, almost all ETL tools can process big data and store it in a data lake (source: the ETL & Data Integration Guide 2024). The ETL tools of ten years ago were not, or very poorly, able to process unstructured data such as videos, audio clips or sensor data. Download the ETL & Data Integration Guide™ 2024īig Data and ETL have had to get used to each other. A 100% independent study that includes up-to-date insights, irrefutable facts and 500 charts. The ETL & Data Integration Guide Quickly unlock a lot of directly applicable knowledge about ETL, big data and data integration and quickly shortlist the ETL tools that meet your criteria.

The amount of the bill you get depends on the size of the data, the number of users or the duration of the ETL process. With “ETL as a service” or “SaaS ETL” you make data integration available on demand. The ETL data integration can take place via and in the cloud (cloud ETL) or simply on an ETL server in your own data center.
