ETL.Staging
: This contains SSIS packages that transfer data fromAdventreWorksLT

ETL.DW
: This contains packages that transfer and transform data from theStaging

We'll have recipes in this section that will explain how the packages are structured and how we'll deploy and run them to load data from the source database to the data warehouse.
