ETL Testing Course | etl testing certification

ETL stands for Extract /Transform Tool. This is a process of extracting data from source systems. ETL help to transform the information into a data type and loads the data in a single repository. ETL refers to the process of verifying, validating, and qualifying data. It also protects the formation of duplicate records and data loss. ETL testing offers the data transfer from the heterogeneous source to the central data warehouse. Data transfer occurs in secured adherence to rules and all valid compliance checks.
