Data Flow Diagrams

Toad™ Data Modeler helps you to create, in addition to the Entity Relationship Diagrams, also the Data Flow Diagrams (DFD). This way you can easily arrange the individual processes in your own model. In the data flow diagram you can make a layout of all Data Stores, Processes, Terminators, including Data flows.

You can download a small instructional movie related to Data Flow Diagrams from the Download section.

Data Flow Diagram reports

Generation of Data Flow Diagram reports is extremely easy. The output document can be either HTML report or RTF report. The HTML report includes all images of all sub processes.

Four Basic Elements of DFD

  • Data flows - represented by named pipelines
  • Processes - represented by circles
  • Terminators - represented by rectangles
  • Data stores - represented by open-ended rectangles
