Venn Diagrams are illustrations used in the branch of mathematics known as set theory. They show the mathematical or logical relationship between different groups of things (sets).
A Venn Diagram was introduced by the British philosopher and mathematician John Venn
(1834-1923) in 1881 and visually shows all the possible logical relations between the sets. This diagram can be interpreted as the relationships of sets which may have some (but not all) elements in common.
Example 1. Venn Diagram - Relationship Marketing
The combined area of sets in a Venn Diagram is called the union of sets. Sometimes there is a rectangle around the Venn diagram to show the space of all possible elements. This rectangle represents so-called Universal set. A Venn Diagram is usually used to divide up two or more objects to highlight similarities and differences.
Venn Diagrams visualize all the possible logical relations between sets. They are used to illustrate simple set relationships in logic, statistics, mathematics, sociology, philosophy, marketing, etc. Venn Diagrams are also commonly used to visually summarize the status and future viability of a project.
Example 3. Venn Diagram - Sustainable Development
There are some similar diagram types, based on Venn Diagram:
- Euler diagrams similar to Venn Diagrams, but they may not describe all the possible relations.
- Johnston diagrams, which are used to illustrate statements in propositional logic, such as "Neither A nor B is true", and are a visual way of illustrating truth tables.
- Karnaugh maps or Veitch diagram are another way of visually representing Boolean expressions.
- Peirce diagrams, devised by Charles Peirce, are extensions to Venn diagrams which include information on existential statements, disjunctive information, probabilities, and relations.
Example 3. Venn Diagram - Knowledge
This simple example was created in ConceptDraw DIAGRAM using the Business Diagrams Solution. It shows the use of Venn Diagram to compare two people groups. One circle represents all the information people know about the stock market in Britain, the other circle represents all the information they know about stock market in Germany. Any features the two areas share can be written in the intersection of the circles. The result shows at a glance what the two markets have in common and what features are different.
Use Business Diagrams solution to quick and easy design your own Venn Diagram of any complexity.
The Venn Diagrams designed with ConceptDraw DIAGRAM are vector graphic documents and are available for reviewing, modifying, converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio), printing and send via e-mail in one moment.

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.

This example shows the 3 Circle Venn Diagram. The Venn Diagrams visualize all possible logical intersections between several sets. On this example you can see the intersections of 3 sets. Venn Diagrams are widely used in mathematics, logic, statistics, marketing, sociology, etc.

Venn Diagrams visualize all possible logical relations between several sets and are widely used in mathematics, logic, statistics, marketing, sociology, etc.
This Venn Diagram shows the relative complement of the set A with respect to the set B. It is the set of the elements in B, but not in A. In other words it is the set-theoretic difference B-A.

A flowchart is a powerful tool for examining processes. It helps improving processes a lot, as it becomes much easier to communicate between involved people, to identify potential problems and to optimize workflow. There are flowcharts of different shapes, sizes and types of flowchart vary from quite basic process flowcharts to complex program flowcharts. Nevertheless, all these diagrams use the same set of special symbols like arrows to connect blocks, parallelogram to show data receiving or rectangles for showing process steps.
Basic flowcharts are used to represent a simple process algorithm. A basic flowchart notation consists of rectangles (business processes), arrows (the flow of information, documents, etc.). The same notation is used in items such as the "decision", which allow you to do the branching. To indicate the start of the entire business process and its termination can be used the "Terminator" element. The advantages of Basic Flowchart are simplicity and clarity. With it you can quickly describe the business process steps. Creating of Basic Flowchart does not require any special knowledge, as easily understand by employees with different levels of education and IQ.
