Final answer:
In the loading phase of an ETL tool, the transformed data gets loaded into a Data warehouse. A staging area, source system, and data lake are other components involved in the ETL process.
Step-by-step explanation:
In the loading phase of an ETL tool, the transformed data gets loaded into an end target which is usually the Data warehouse. The data warehouse is a central repository that stores data from various sources, allowing for efficient data analysis and reporting.
A staging area is used to temporarily store data during the ETL process, but it is not the final target for the transformed data. The source system is the system where the original data resides before being processed. A data lake is a storage repository that holds a large amount of raw data in its native format for future processing and analysis.
