Summary
A data lake plays a central role in the modern data warehouse architecture. In this chapter, you learned what a data lake is. You learned what zones a data lake may consist of and how to set up a folder structure for those zones. You also learned about some different file formats to use.
You implemented a data lake by provisioning an Azure storage account.
The next chapter will give you a high-level insight into how to copy data from source systems into a data lake and how to propagate the data further downstream.
