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

How do Fishbone diagrams solve manufacturing problems? Fishbone diagrams are successfully used in various fields of industries and manufacturing to analyze the set of possible causes and their effects. Fishbone diagram provides a process to clearly define the “Effect” and then puts you to thinking about the possible causes, based on the categories of common problems in manufacturing.
ConceptDraw DIAGRAM application extended with Fishbone Diagrams solution lets you construct Fishbone diagrams and represent globally recognized standards for manufacturing 6 Ms and 8 Ms.

A workflow diagram is less general notation than a process flow diagram. Workflow as a term can apply to organizational process which involves people, resources, documents, sort of data, for instance; whereas a process is general collection of steps occuring in any sort of activity. That is why process flow diagram can be used as workflow diagram to describe business process, data flow or department interactions.
The fastest way to create a workflow diagram is using pre-designed workflow template. ConceptDraw DIAGRAM with the Workflow Diagrams solution delivers rich set of workflow diagram templates you may start from.

When you are a beginner in software development, you make a lot of mistakes. Developing logical models, or data flow diagrams is a way to see the the whole project and all the processes clearly. And some novices, unfortunately for them, miss modeling stage at the beginning of project life cycle, and get into troubles as the project grows.
This image represents the data flow diagram applying symbols of Yourdon and Coad notation. This DFD depicts the data flow inside an organization department deals with receivables. The icons of standard Yourdon and Coad notation provides possibility to draw professional looking and well- readable DFD for business documentation. This data flow diagram was designed with the help of ConceptDraw DIAGRAM and its Data Flow Diagrams solution. The solution delivers three vector graphic libraries including elements of Yourdon and Coad and Gane-Sarson notations.

The first thing that usually comes to mind when talking about database models is ER-diagrams, and the ways to create them. The second most recognizable notation is the Crow’s Foot, which visually differs from Chen’s notation. Actually, it doesn’t matter which notation you’ll use for your entity relationship diagram (ERD), but the content is what matters.
When designing an Entity-Relationship Diagram one need to use a certain notated symbols that were developed and standardized especially for databases description. First of them - the Chen’s notation had a linguistic origin. It includes rectangle boxes to show entities that may be described as nouns, and the relationships between them described as verbs depicted in a form of diamond. Finally the Chen’s notation was simplified up to the Crow’s Foot notation. It represents a relationship as labeled line. It is precisely this notation is shown in the given figure. ConceptDraw DIAGRAM together with its Entity-Relationship Diagram (ERD) solution is designed to support professionals who deals with creating ER diagrams using the element of both - Chen’s and Crow's Foot notations.

The vector stencils library Crow's Foot Notation from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Crow's foot notation such as relationship symbols and entity symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Entity-Relationship Diagrams (ERD) solution is contained in the Software Development area of ConceptDraw Solution Park.
