What is a feature of calculated columns using graphical modeling tools?

Calculated columns in graphical modeling tools allow for the implementation of nested calculations. This means you can create complex formulas by embedding one calculation within another, thereby enhancing the flexibility and power of your data transformations and calculations. This feature is particularly useful in scenarios where you need to derive values based on multiple preceding calculations or conditions.

For example, a calculated column could be used to first compute a percentage of a value in another column, and then use that percentage in a further calculation, thereby allowing for dynamic and layered data manipulation. This capability empowers developers and analysts to handle more intricate business logic directly within their models without needing to precompute values elsewhere.

The other options do not accurately reflect the functionality of calculated columns. While non-measure attributes can also be incorporated in calculations, the primary innovative aspect lies in the ability to nest calculations, which enhances data analysis complexity. No restrictions to only arithmetic calculations exist, as these calculated columns can include logical functions and various operations. Lastly, the read-only mode does not apply, as calculated columns can often be modified within the graphical interface, although their results may be bound to the underlying dataset dynamically rather than requiring manual updates.
