Summary
We've come to the end of this chapter in which we've been able to use some advanced expression techniques and Set Analysis to build period-over-period comparisons. We have learned the syntax and variations of a set expression.
We also learned how to construct and use Set Analysis expressions to enable time period comparisons, and also how to use some time-saving techniques to re-use set expressions across different documents.
Finally, we learned how to use alternate states for comparative analysis.
Let's now move on to the next chapter, which expands on the concept of data transformation at an advanced level.
