ETL stands for which process, and what does it do?

• A. ETL stands for Extract, Transform, and Load; it moves data from Chronicles to a relational database on a dedicated reporting server.
• B. ETL stands for Extract, Transform, and Load; it moves data from Chronicles to a relational database but only stores it in a staging area.
• C. ETL stands for Evaluate, Test, and Load; it moves data within Chronicles.
• D. ETL stands for Extract, Transfer, and Load; it duplicates data.

Answer: (A)

ETL means Extract, Transform, Load. It describes pulling data from a source system, converting and cleaning it to fit the target schema and business rules, and then loading it into a target relational database. The best description matches this flow by saying data is moved from Chronicles (the source) into a relational database on a dedicated reporting server, making it ready for analysis and reporting. The other options mix up the terminology (Evaluate instead of Extract, or Transfer instead of Transform) or describe loading into a staging area or duplicating data, which aren’t the standard ETL pathway.
