Which tool is utilized to combine two data streams using common fields or record positions?

1. Join

2. Sort

3. Formula

4. Filter

The correct answer is: Join

The tool used to combine two data streams based on common fields or record positions is the Join tool. This tool effectively merges datasets by matching records that share specific attributes, allowing for a unified view of the data. When using the Join tool, users can specify the fields (known as keys) on which they want to join the datasets, ensuring that only relevant records are combined. This capability is critical in data preparation and analysis, as it allows for the integration of different data sources, leading to more comprehensive insights. The Join tool also provides options to handle cases where there are records that do not match between the two streams, allowing users to choose how they want to handle such discrepancies (e.g., inner join, left join, etc.). In contrast, the other tools mentioned have different functions: Sort is used to arrange records in a specified order, Formula allows for creating or modifying data fields through calculations, and Filter is used to exclude records based on certain conditions. These tools serve important roles in data manipulation and preparation but do not specifically focus on the combination of data streams like the Join tool does.
