What capability does the append fields tool provide?

1. It allows you to search for and replace values in a data stream

2. It enables the combination of fields across multiple records

3. It duplicates each record of a target input for every record of a source input

4. It pivots data orientation from horizontal to vertical

The correct answer is: It duplicates each record of a target input for every record of a source input

The append fields tool is designed to duplicate each record of a target input for every record of a source input. This creates a Cartesian product, meaning that every record in the source input is matched with every record in the target input. This functionality is especially useful when you need to enrich your data by combining static information (from the target input) with dynamic data (from the source input) without altering the original data structure. For example, if you have a list of products as your target input and a list of sales transactions as your source input, using the append fields tool would allow you to see each product matched against every transaction, which can be invaluable for analysis or reporting purposes. Other options do not align with the specific capabilities of the append fields tool. For instance, searching for and replacing values in a data stream focuses on data manipulation rather than combining records. The ability to combine fields across multiple records sounds similar but refers more to summarizing or aggregating data, which isn’t the primary function of the append fields tool. Additionally, pivoting data orientation from horizontal to vertical is related to reshaping data rather than appending. Hence, the primary purpose and correct understanding of the append fields tool lies in its ability to duplicate records, generating comprehensive
