How does Workday check for duplicates during data loading?

Workday employs built-in validations during data loading to check for duplicates, primarily using key identifiers that uniquely identify each record, such as employee IDs or transaction numbers. This method ensures that as data is being loaded into the system, any potential duplicates are identified based on these critical identifiers, allowing for real-time validation and error handling.

This proactive validation process is essential for maintaining data integrity and avoiding duplication issues that could disrupt operations or data reporting. By automatically checking against established rules for key identifiers, Workday helps implementers streamline the data loading process and ensures that users have clean, unique records in their system right from the start.

The other options do not effectively address the mechanism Workday uses for duplicate detection. Random sampling records would not provide a comprehensive approach to identify duplicates. Relying on user feedback after loading is too late in the process to address duplicates. Comparing records against a database is not specifically how Workday implements its validation, as the key identifiers are the main focus for detecting duplicates timely and efficiently.
