Designer allows you to manage how the data flows between the Identity Vault and the connected systems. You can see how the data flows between all of the connected systems, make changes as needed, create reports about the data, and view the flow of passwords between the systems.
The Dataflow view and the Dataflow editor manage the data. The Dataflow view displays the flow of data in the modeler per driver. The Dataflow editor displays a more granular view.
