What is ETL Testing?
ETL- Extract, Load, Transform – as the name implies is all the processes and technologies that revolve around finding the data, formatting it as needed and loading it to the relevant database systems for retrieval and usage. Data’s importance and its key role in the current day’s market is no secret. It is extremely important more than before to make sure that the ETL processes around the data are reliable, accurate and productive in order to ensure that the Business intelligence and data warehouse systems are everything they are supposed to be.
