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
You need to draw the Data Flow Diagram? Use ConceptDraw DIAGRAM diagramming and vector drawing software extended with Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.

This template shows the Context Diagram. It was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Block Diagrams Solution from the “Diagrams” area of ConceptDraw Solution Park.
The context diagram graphically identifies the system. external factors, and relations between them. It’s a high level view of the system. The context diagrams are widely used in software engineering and systems engineering for designing the systems that process the information.

It doesn’t matter what kind of business you have, a bar or a gym, there are common concepts for any of them. One of those concepts is accounting, and to facilitate the work with the figures, you can use accounting flowchart symbols and create a clear and representative scheme. You can create flowchart for auditing, tax accounting and even for planning your own budget.
A graphical tool for displaying successive processes is flowchart. This method is mostly suited to represent an accounting process. The sequence of steps in the accounting process usually consists of standard accounting procedures, that can be depicted by using a minimal number of symbols, applied for the basic flowcharting. The advanced opportunity to create professional Accounting Flow charts is provided by ConceptDraw Accounting Flowcharts solution. It includes contains a library of accounting flowchart symbols used when drawing the accounting process flow.

The diagrams with highest level in the hierarchy define the main processes or subsystems with external and internal data sources. To detail them, DFD Library is used to build a system of lower level diagrams. This decomposition continues hereinafter it is meaningless.
This data flow diagram of a system of a library management is a context-level DFD. The data flow diagram of this type depicts the large system as a solid process, and does not input any explanation of its content. It is an ordinary practice - creation of a context-level data flow diagram when starting system development. This DFD was made using ConceptDraw solution designed especially for data flow diagrams development. One can find out Data Flow Diagrams Solution in a Solution Park of ConceptDraw and can use in as addition to the common Conceptdraw DIAGRAM diagramming tools.
