ETL is a critical component of data warehouse architecture. ETL extracts data from source systems, transforms it into a consistent data type, and loads it into a single repository (Extract, Transform, and Load). Data validation, evaluation, and qualification are crucial components of ETL testing. After extracting, transforming, and loading the data, we perform ETL testing to ensure that the final data was imported into the system in the correct format.
