Azure: Building ETL/ELT Workloads

Extract, transform, and load (ETL) is a common process in many businesses, pulling out data from one database, manipulating that data, and then importing it into another location, such as another application database or a data warehouse. With extremely large volumes of data, businesses are also taking advantage of extract,load, and transform (ELT), where the data first is loaded into an operational datastore (ODS) or data lake and then is transformed.
