The process of moving data into a data warehouse from multiple sources is called ETL:
Extract: Gathering information from many source systems.
Transforming the extracted data into a structure or format that is appropriate for analysis and querying is known as transformation. This could entail making sure the data is consistent, eliminating duplicates, and cleansing the data.
Loading: Putting the converted data into the database or data warehouse of choice.
