Power Query seems to be the easiest way to do ETL. Just click in the ribbon and your data and your data is automatically cleaned. Things get more complicated when you need more queries for your model. If you don't create structure, queries tend to get messy.
This session is all about structuring your M-language queries. Using groups, local and global parameters, documentations in the M-language statement creates a profound structure. Before you know, you create small, but beautiful M-code. This session is not rocket-science, but we like to trigger your common sense and bring you the ability to get and write better, more efficient queries.
