In this chapter, you learned that DAX allows you to significantly enhance your data model by improving the analytical capabilities with a relatively small amount of code. You also learned how to create calculated columns and measures and how to use DAX to perform useful time series analysis on your data. This chapter merely scratched the surface of what is possible with DAX. As you further explore the DAX language on your own, you will quickly become a proficient author of DAX formulas. As with everyone who learns DAX, you will inevitably learn that there is a layer of complexity to DAX that will require further education to really master. When you get to this point, it would be advantageous to look for classes or books that will help you to truly master DAX!
