What does the source sequence reconciliation rule do in Identity Resolution?

The source sequence reconciliation rule is essential in Identity Resolution as it establishes the priority of specific data sources when constructing attributes within a unified profile. This means that when data from various sources is combined to create a coherent view of an individual or entity, the reconciliation rule determines which data source takes precedence. By setting a priority, organizations can ensure that more reliable or relevant data feeds into the unified profile, enhancing its overall accuracy and usefulness.

In contrast, the other options describe relevant but different functionalities in data management or identity resolution. For instance, gathering source data from disparate systems is essential for building a comprehensive dataset, but it does not specifically relate to the reconciliation of those sources. Reconciliation based on frequency concerns the valuation of data but doesn’t prioritize particular sources in the reconciliation process. Lastly, sorting data sources by preference can inform the reconciliation strategy, but it does not directly set the priorities for attributes within the profiles themselves. Thus, the correct choice focuses precisely on the role of prioritization in the reconciliation of data sources to optimize the unified profile's quality.
