Which databases can ETL load into?

Which databases can ETL load into?

• A. Oracle
• B. Microsoft SQL Server
• C. Teradata
• D. All of the above

Answer: (D)

The ability to load data during ETL depends on the compatibility between the ETL tool and the target database. In practice, ETL platforms provide connectors or adapters for major relational databases, allowing data to be written directly into those systems. Oracle, Microsoft SQL Server, and Teradata are all common targets with well-supported loading paths, so a typical ETL setup can deliver data to any of them as a destination. Because each listed database is a valid target, selecting all of the above best captures the range of possibilities an ETL process can load into. Remember that you’ll need the right drivers, permissions, and proper data-type mappings, but the capability to load into these databases is standard.
