ERD Symbols and Meanings

ERD Symbols and Meanings
Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

Flowchart Programming Project. Flowchart Examples

Design Pictorial Infographics. Design Infographics

In the course of recent decades data visualization went through significant development and has become an indispensable tool of journalism, business intelligence and science. The way visual information may be conveyed is not limited simply to static or dynamic representation, it can also be interactive.

Second level can be defined as a visualization of knowledge, depiction of thoughts and ideas in the form of images or diagrams.
