This Logical Data Flow Diagram (DFD) template is designed to visually model the high-level, essential flow of information and processes within any system. It is an essential analytical tool for system analysts, business process owners, and project managers focused on system requirements. Users begin the workflow by defining the External entity (like people or organizations) which interacts with the system. Data flows from the entity to a Process step, which transforms or manipulates the data before sending it to a Data store (database or file). The process concludes by tracing the processed information as it flows through subsequent steps and back to an External entity. The resulting DFD provides a clear, documented view of the system's operational logic, ensuring accurate design based on business requirements.
