The Full form of ETL is Extract, Transform and Load. It is a process in which we format the extracted data to store or to refer to in future. In the present technological era, “data” is important because almost every business is revolving around the data. Latest applications and working methodologies need live data for processing, so to fulfil those requirements, many open-source and commercial ETL tools are available in the market. In this article, we will study some open-source ETL Tools that are available in the market.
