Data Flow Diagrams provide a clear understanding of the flow of data through the systems, processes, and users within your organization.

Examples of errors include forgetting to include a data flow or pointing an arrow in the wrong direction. A key reason why keeping data flow diagrams up-to-date is to address issues of system growth.

The flow chart shown overleaf illustrates the use of the Database Interface routines. Routine DIERR is not included in the diagram. It may generally be used out of sequence within the guidelines ...

Here we predict compositional and thermal heterogeneity in this region, using viscous-flow calculations based on the new viscosity profile, together with independent mineral physics data.
