From which source database does the ETL process extract data?

Explanation:
ETL pulls data from Chronicles. In this context, Chronicles is the operational database that stores transactional data, and the ETL process extracts information from it, then transforms and loads it into Clarity, the reporting/analytic data store. Clarity is the destination in this flow, not the source. Oracle and SQL Server are general database platforms and aren’t specified as the source database in this scenario, so they don’t fit as the answer here.
