A dataset precedence merge policy prioritizes datasets based on which attribute?

The prioritization of datasets in a merge policy is fundamentally guided by the concept of the "source of truth." In this context, the "source of truth" refers to the authoritative dataset that is considered the most reliable representation of the data. When determining which datasets to merge, a precedence merge policy prioritizes those that are closest to this authoritative source. This means that if multiple datasets contain overlapping information, the one that is deemed to originate from the most credible and authoritative source of truth will take precedence.

This principle is vital because relying on an authoritative dataset helps ensure data integrity and accuracy when making decisions or undertaking actions based on the merged data. It minimizes discrepancies and inconsistencies that could arise if less reliable sources were given priority.

Other attributes such as data freshness, volume of data, and data format compliance can be important in certain contexts but are secondary to the fundamental principle of aligning with the source of truth in a precedence merge policy. By focusing on the authoritative origin of the datasets, organizations can maintain a high standard of data quality.
