What is balanced data flow diagrams?

Balanced data flow diagrams (DFDs) are graphical representations that illustrate the flow of data within a system while ensuring consistency between different levels of detail. They maintain a balance between high-level and low-level diagrams by ensuring that the inputs and outputs of processes at one level match those at another. This consistency helps to avoid errors in system design and ensures clear communication among stakeholders. Balanced DFDs are crucial for effective analysis and design of information systems.
