Summary
In this chapter, we learned about a lot of functions we can use to concatenate, merge, join, aggregate, and group data. All these functions will give you a lot of power to wrangle your data and shape it the way you need in order to get insights from it, reformat your dataset for different uses, and combine multiple datasets to get a better resolution of your data in the same dataset.
In the next chapter, we will learn about the functions that Optimus provides for profiling data so that we can get a better picture of it.
