Dataflow is a tool that has been around in the Power BI service for a very long time , and is used to import, transform, and load data into a semantic model (ETL). Practically, it is Power Query in a cloud environment.

The OneLake catalog is a feature within Microsoft Fabric that works as a centralized place to store, find, analyze data.
