What is ETL Process: Managing Dirty Data Issues about?

The ETL process involves 3 main steps: extract, transform, load. Data is extracted from different source systems, transformed to be consistent and clean, and then loaded into the target data warehouse. ETL is a complex process due to the diversity of source systems, inconsistent data representations, complex transformations required, and large volumes of legacy data that must be handled.
