A developer needs a Data Mapper that queries Salesforce records and returns them as structured JSON to a calling component, with no writing. Which Data Mapper type is this?

選択肢

1. Extract, which reads Salesforce records and outputs structured JSON to the caller.
2. Transform, which queries Salesforce directly and returns the records as JSON nodes.
3. Turbo Load, which is the high-speed read type that returns JSON from Salesforce to the caller for display.
4. Load, which reads Salesforce records and returns them as JSON without writing anything.
