Venn Diagram Examples for Problem Solving. Venn Diagram as a Truth Table

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 shows all the possible logical relations between the sets.

Design Element: Chen for Entity Relationship Diagram - ERD

Entity-Relationship Diagrams (ERDs) were developed and introduced as a convenient and visual tool for the data modeling, they are the perfect way for easy determining data and also relationships between them. The first standard notation for ERD was proposed by Chen. Chen's notation is very rich on the data modeling tools and standard notation symbols and elements for drawing easy understandable Entity-relationship diagrams, Attribute diagrams, Decomposition charts, which are especially popular for designing relational databases. The entity is the main term, it is a set of instances abstract or real objects with common characteristics or attributes. Any system's object is represented by one uniquely identified entity, relationships describe the links between the entities. ConceptDraw DIAGRAM diagramming software, which includes the Entity-Relationship Diagram (ERD) solution, offers all needed tools for professional drawing ER diagrams. Specially developed vector ERD design elements according to Chen and Crow's Foot notations are indispensible for professional ERDs design.

E-R Diagrams

Complexity of databases increases day by day, due to this the Entity relationship models and E-R diagrams become more and more popular, and now are an important part of database design. E-R diagrams created at ConceptDraw DIAGRAM allow visually and graphically represent structure and design of databases.
