Which of the following describes a key feature of the append fields tool?

1. It cleanses data of errors and inconsistencies

2. It allows duplication of target records for each source record

3. It summarizes the data into a cross-tabulation

4. It moves null values from one field to another

The correct answer is: It allows duplication of target records for each source record

The append fields tool is designed to enhance data by combining fields from one data source with records from another. A key feature of this tool is its ability to append data from source records to target records, effectively duplicating the target records for each matching or related source record. This is particularly useful in scenarios where you want to enrich a dataset by adding more information without losing the context of existing records. By allowing for the duplication of target records for each source record, the append fields tool enables users to maintain the integrity of both datasets while expanding the available information. This functionality is crucial in data preparation and analysis, especially when working with datasets that require the combination of many attributes for comprehensive analysis. The other options describe functionalities that are not characteristic of the append fields tool. For instance, cleansing data relates to the data cleansing tools, summarizing data into a cross-tabulation is typical of the cross-tab tool, and moving null values between fields might involve data preparation techniques but is not a primary function of the append fields tool.
