Aggregating data with a Row Denormaliser step

In the previous section, you learned how to use the Row Denormaliser step to combine several rows into one. The Row Denormaliser step can also be used to take a dataset as input and generate a new dataset as an output with aggregated or consolidated data. Let's see how the Row Denormaliser step works with an example.
