On which survivorship rule is the calculation of the best record based on?

The survivorship rule based on completeness focuses on ensuring that the most comprehensive and relevant information is retained when merging records from various sources. In the context of data governance, when evaluating records, completeness refers to the extent to which all mandatory data fields are filled or populated within a record.

By selecting the record that holds the highest degree of completeness, organizations can ensure that they utilize the most informative and meaningful data available. This becomes particularly vital in scenarios where certain records may have missing information, which can significantly impact decision-making. Therefore, prioritizing the completeness of the records ensures that the resulting dataset is as rich and useful as possible.

The other options—accuracy, recency, and uniqueness—do not primarily address the integrity of a dataset in terms of filling all relevant data points, highlighting how completeness stands out as a crucial survivorship rule in data management.
