    ETL means Extract, Transform, and Load. It is a process carried on hefty data. It extracts data from the source, transforms it, and then loads it on the target depository. ETL includes the steps of validating, verifying, quantifying, and checking data for various critical data points. Throughout the process, the maintenance of data integrity and curbing any possible duplication, loss, and manipulation of data are critical. To achieve all the objectives of the ETL process, there emerges a need for specialized ETL testing tools that can process data efficiently without any loopholes or bottlenecks. Thankfully, there are a plethora of ETL testing tools available to choose from. Some work well in fulfilling the needs of a full-fledged enterprise, while some others fit perfectly with small team collaboration requirements.
