Data is of utmost importance in digital systems. Protecting data, therefore, is of utmost importance. ETL refers to Extract, Transform, and Load. It supports the movement of data from its source to storage. With ETL testing we ensure that the data is not lost or corrupted during this movement. Huge volumes of data are collected in various formats and sources. The mapping process of these data is error-prone and can have quality issues.
