Gane-Sarson Notation for data flow diagrams. Born in England, Sarson obtained her BA in Zoology and Chemistry at the Royal Holloway, University of London in the 1960s.

Data Flow Diagram Symbols. DFD symbols are consistent notations that depict a system or a process. It entails the use of short-text labels, arrows, circles and rectangles to describe data flow direction. Also forming part of DFDs are varied sub-processes, data storage points, and data inputs and outputs. A data flow diagram has four basic elements. Data Flow Diagram (DFD)s: An Agile Introduction. In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system, showed how the data moved from one process to another, as well as its logical storage. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system).The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops. Specific operations based on the data can be represented by a flowchart.

There is also the symbol system of Gane and Sarson, but in our data flow diagram examples, we will use Yourdon and Coad symbols as they are easier for drawing and remembering. DFD rules, guidelines, and tips: Creating data flow diagrams requires some guidelines and rules that should be followed. The focus of analysis in the Gane and Sarson method is the Data Flow diagram, which is used to describe the processes of the system, and how the processes ... Both Yourdon-Coad and Gane-Sarson uses squares to represent external entities, arrows to represent data flow and rectangles to represent data stores. The main difference between two notation is that Yourdon-Coad uses circles to represent processes whilst Gane-Sarson utilizes rectangles with rounded corners, better known as lozenges. Data flow diagram (DFD) is the part of the SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human ...
