What should be done if you need to identify duplicate records in a dataset?

The Unique Tool is specifically designed for identifying and removing duplicate records in a dataset. When you use this tool, it examines the values in the specified fields and groups records based on those values. The Unique Tool separates the dataset into two outputs: one containing the unique records and another containing any duplicates found. This makes it particularly effective for cases where the goal is to discern which records appear more than once in the data.

While the other tools listed have their own functionalities, they are not tailored specifically for identifying duplicates. The Join Tool is used to combine datasets based on common keys but does not inherently identify duplicates. The Data Cleansing Tool focuses on preparing data by removing unwanted characters and formatting issues, and the Filter Tool segments data based on specified criteria but does not provide a straightforward method for detecting duplicates. Therefore, the Unique Tool stands out as the most appropriate choice for directly identifying duplicate records in a dataset.
