What is Data Flow Diagram? - Visual Paradigm Grey holes - A processing step may have outputs that are greater than the sum of its inputs Data Store A data store or data repository is used in a data-flow diagram to represent a situation when the system must retain data because one or more processes need to use the stored data in a later time. Notation
Data flows: Note on Data-Driven Process ... - Babson College Summary and next steps . Data flow diagrams can assist in Isolating the component parts of a business process, reducing the analytical complexity involved in determining the specifications that process support software would have to meet.; Shifting the focus of a process description to the data flows and processing steps that the process represents.
Developing DFD Model of System - GeeksforGeeks A bubble representing a process should have minimum one input and one output flow. When a bubble has input flow without any output flow, it is known as "black hole". When a process has output flows but no input flows, it is called a "miracle". A processing step may have outputs that are greater than sum of its inputs is called Grey holes.
Data Flow Diagrams - SlideShare A gray hole is a process that has at least one input and one output, but the input obviously is insufficient to generate the output shown. For example, a date of birth input is not sufficient to produce a final grade output in the CALCULATE GRADE process.
