We've come to the end of this chapter where we've been able to use some advanced techniques for data aggregation and advanced expressions. We have learned how to use variables in QlikView and embed them into expressions.
We also learned the use of conditional expressions, with the If function, to output results based on logical comparisons.
Finally, we learned how to use advanced and nested aggregations in charts.
In the next chapter, we will be learning about Set Analysis, one of QlikView's most powerful functionalities, and how it can be used for Point In Time reporting.
