Data Flow Model Diagram Software
It contains special shapes and settings for creating data flow model diagrams or diagrams of public exposed interfaces, COM interfaces, and OLE interfaces in object-oriented programming.

- No prior drawing experience required.
- Fast generation of DFD through predefined symbols.
- Quick start from ready-made DFD templates.
- Seamless integration with MS programs. Flexible export with broad file format compatibility.
- Software designers: Model how data is processed by a system using Gane-Sarson (DFD) notation.
- Software developers: Write pseudo-code for an existing process data flow.
- Development managers: Describe nested layers of data flow throughout systems.
The following templates are described with respect to these conventions. These EdrawMax templates include nodes with a sub-paging feature that facilitates creating subordinate diagrams and navigating multi-tiered models after a design has been completed.
The formal, structured analysis approach employs the data-flow diagram (DFD) to assist in the functional decomposition process. It conquers advanced structured analysis techniques, and those techniques are representative of present conventions. To summarize, DFD's are comprised of four components:
- External interactors are represented by a rectangle.
- Data stores are displayed by an open rectangle (2 or 3 sides).
- Processes are represented by any rounded object (a circle, oval, or square with rounded corners). A DFD process may represent system function at one of various levels, atomic through aggregate.
- Data flows are represented by arrows, with labels indicating their content.
