A data flow diagram is your guide to understanding the nitty-gritty of how information travels within a system — such as databases, software applications, and business processes. While a flowchart also visualizes flows, it isn’t limited to representing data. Flowcharts are versatile maps that outline processes, decisions, and actions much more broadly. Miro's free data flow diagram template is specially crafted to visualize the intricacies of data flow within complex systems.
