Selected Answer: D
See pg 113 - 3.6 Data Mapping - This section describes data mapping, which involves consolidating data from various sources into a standardized format for easier access and reporting. This process requires a structured approach to ensure that data is accurately transformed and integrated, which aligns with the idea that querying is a structured method for handling data.
