Which statement best describes Chronicles in the ETL process?

• A. Chronicles is the source database from which data is extracted
• B. Chronicles is the destination database for loaded data
• C. Chronicles is a data visualization tool
• D. Chronicles is the ETL tool itself

Answer: (A)

Chronicles is the source database from which data is extracted. In an ETL flow, you start by connecting to source systems to pull the raw data, and Chronicles represents that starting point for the data you want to move and transform. After you extract and transform the data, it is loaded into a destination such as a data warehouse or another target store. Chronicles isn’t where the data ends up (that would be the destination), nor is it a data visualization tool. It also isn’t the ETL tool itself—the ETL tool handles the extract, transform, and load steps, while Chronicles is simply the source being read from.
