Which of these is a deliverable that ensures the integrity of data assets?

The deliverable that ensures the integrity of data assets is data audit trails. Data audit trails provide a means of tracking changes and access to data over time, enabling organizations to verify the accuracy and reliability of their data. This includes logging who accessed the data, what changes were made, and when these changes occurred, thereby ensuring a clear historical record of data integrity.

Data marketing strategies focus on promoting and selling data products rather than maintaining data integrity. Data architecture documentation outlines how data flows and is structured within an organization but does not directly ensure that the data remains accurate or reliable over time. Data security policies are vital for protecting data from unauthorized access or breaches but do not inherently track the integrity of the data itself. In summary, data audit trails uniquely provide the necessary mechanisms to confirm and maintain the integrity of data assets.
