This technical note presents an adaptation of the data flow diagram (DFD) technique whereby each data store symbol represents a database rather than a single table. It is conjectured that this modification makes DFDs easier to create, understand, and maintain. It also reduces an overlap with the entity-relationship diagram technique by curtailing graphical manifestations of the data model in the DFD.
