Summary
You completed the first step in your journey and should be pleased with yourself as ETL is not trivial or simple. In this chapter, you learned how to execute an ETL process from start to finish. This includes knowing how to extract data from multiple sources, including databases. Then, you transformed the data with the dplyr package and exported the information into a file that could be loaded into a business system.
In the next chapter, you will learn how to clean data once it is loaded. You will see that, like ETL, data cleaning is a broad and multi-faceted aspect of business intelligence and analytics.
