Data scrubbing can help upgrade data quality; it is not a long-term solution to the data quality problem.
Answer: A
Correct answer: True
Scrubbing improves the data going into the warehouse but leaves the source systems producing the same errors next time, so the cleaning must be repeated at every load. The lasting remedy is to correct the operational processes, which is why quality is treated as a management programme rather than a stage in ETL.
