Data flow diagrams (DFD) are commonly used in system analysis and design to represent the flow of data within a system. Analysts can spot black holes, which are areas where data goes in but never comes out, and miracles, which are areas where data appears without being input, simply by examining the DFD. Context diagrams, entity relationship diagrams, and structured English are also useful tools for system analysis, but they do not provide the same level of detail about the flow of data within a system.
