But one of the roles of the ETL (Extract, Transform, Load) process is to identify and correct erroneous or inconsistent data. During the Transform phase, data may be cleaned, transformed, and validated to ensure that it meets the desired quality standards.
This can include identifying and fixing errors such as missing or incorrect data, duplicates, and inconsistencies.

ETL: Extract, transform, and load (ETL) is a process in database usage and especially in data warehousing that involves:
1. Extracting data from outside sources
2. Transforming it to fit operational needs (which can include quality levels)
3. Loading it into the end target (database or data warehouse)
Hope this help you. Have a nice day!
