Data is extracted from source systems, transformed into a consistent data type, and then loaded into a single repository during the Extract/Transform/Load (ETL) process. The process of evaluating, confirming, and certifying data while avoiding duplicate records and data loss is known as ETL testing.
ETL Testing has gained immense popularity across the globe resulting in huge demand for certified professionals.
Why is ETL Testing important?
The ETL testing process makes sure that all criteria are met and that the transformation rules are followed while transferring data from many sources to a single repository. Additionally, the procedure helps in the early discovery and reduction of flaws and faults. This:
Shorten the delivery time.
Reduce Wasteful Spending.
Automate Difficult Processes
data validation before migration
Build feedback loops for data quality.
Change the data.
Creating Transparency in the Process.
consistency in data transfers
ETL Testing certified professionals, executives and managers are in high demand in companies across the globe.
