Data Flow Diagram Examples
Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.
DFDs consist of four major components:
- data stores,
Example 1. Data Flow Diagram Symbols
The symbols used to depict how these components interact in a system are simple and easy to understand.
A Data flow diagrams used for:
- Graphical representation of the "flow" of data through an information system
- Modeling process aspects
- An overview of the system
- For the visualization of data processing
- Structured design

TEN RELATED HOW TO's:
There are many tools to manage a process or to illustrate an algorithm or a workflow. Flowcharting is one of those tools. However, it may be difficult to show complex processes that require multiple attributes or several people in a simple flowchart, so a cross-functional flowchart would be a solution for that situation. To create such flowchart, group processes and steps to labeled rows or columns, and divide those groups with horizontal or vertical parallel lines. It is worth mentioning that there are different types of cross-functional flowcharts, like opportunity or deployment flowchart.
This diagram shows a cross-functional flowchart that was made for a trading process. It contains 14 processes, distributed through 5 lines depicting the participants who interact with the process. Also there are connectors that show the data flow of information between processes. The cross-functional flowchart displays a detailed model of the trading process, as well as all participants in the process and how they interact with each other. The lines in the flowchart indicates the position, department and role of the trading process participants.

This sample shows the Flowchart of the Sustainment and Disposal.
A Flowchart is a graphically representation of the process that step-by-step lead to the solution the problem. The geometric figures on the Flowchart represent the steps of the process and are connected with arrows that show the sequence of the actions. The Flowcharts are widely used in engineering, architecture, science, analytics, government, politics, business, marketing, manufacturing, administration, etc.
