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.

When we start to speak about databases, we must always mention database structure visualization. One of the most common ways to do it is to create an entity relationship diagram, and to put appropriate symbols on it. It is important either for database projecting and for its' future maintenance.
Entity Relationship Diagram describes data elements and their relationships within a database. There are a set of special symbols that depict each element of an entity relationship diagram. Entities - represents some stable components such as supplier, employee, invoice, client, etc. Relation symbols show how the entities interact. Attributes define characteristics of the relationships. Attributes can be one-to-one or many-to-many. Physical symbols is used in the physical models. They represent items such as fields, tables, types and keys. ERD physical symbols are the building material for the database. Notation lines are used to illustrate the relationships. The most common method is Crow’s Feet notation. You can use ConceptDraw Entity-Relationship Diagram (ERD) solution to represent a database using the Entity-Relationship model.

A database is a data collection, structured into some conceptual model. Two most common approaches of developing data models are UML diagrams and ER-model diagrams. There are several notations of entity-relationship diagram symbols and their meaning is slightly different. Crow’s Foot notation is quite descriptive and easy to understand, meanwhile, the Chen notation is great for conceptual modeling.
An entity relationship diagrams look very simple to a flowcharts. The main difference is the symbols provided by specific ERD notations. There are several models applied in entity-relationship diagrams: conceptual, logical and physical. Creating an entity relationship diagram requires using a specific notation. There are five main components of common ERD notations: Entities, Actions, Attributes, Cardinality and Connections. The two of notations most widely used for creating ERD are Chen notation and Crow foot notation. By the way, the Crow foot notation originates from the Chen notation - it is an adapted version of the Chen notation.
