# Example of DFD for Online Store (Data Flow Diagram) DFD Example

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.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

## Venn Diagram Examples for Problem Solving. Computer Science. Chomsky Hierarchy

A Venn diagram, sometimes referred to as a set diagram, is a diagramming style used to show all the possible logical relations between a finite amount of sets. In mathematical terms, a set is a collection of distinct objects gathered together into a group, which can then itself be termed as a single object. Venn diagrams represent these objects on a page as circles or ellipses, and their placement in relation to each other describes the relationships between them.
The Venn diagram example below visualizes the the class of language inclusions described by the Chomsky hierarchy.
