Data Flow Diagramming
Data Flow Diagramming (DFD) is a visual modeling technique used to represent the flow of data through a system, showing how data is processed, stored, and transferred between components. It helps in analyzing, designing, and documenting information systems by illustrating the movement and transformation of data. DFDs are commonly used in software engineering, business analysis, and system design to clarify requirements and identify potential issues.
Developers should learn Data Flow Diagramming when working on system analysis, software design, or business process modeling to visualize data dependencies and improve communication with stakeholders. It is particularly useful in the early stages of development for requirements gathering, identifying bottlenecks, and ensuring data integrity in complex systems like enterprise applications or data pipelines.
