Not sure, but IMO a dataflow diagram from good ol' SSADM got a lot of the way there. Unlike a lot of the modern techniques which model (groups of) deployed components, DFDs were strictly logical and functional and included data stores and users as well as functional components. So it was possible to model data in flow and at rest, and the characteristics of each, including where it crossed system boundaries.
IMO this was the best diagram format to get an overall view of the system, or reveal which areas needed further analysis.
