ERD Symbols and Meanings

Entity Relationship Diagram Symbols and Meaning - crow's foot notation

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 PRO.

How to Create an ERD Diagram

Entity-Relationship Diagram (ERD) using Chen's notation

ERD (entity relationship diagram) is used to show the logical structure of databases. It represents the interrelationships between components of database (entities). Entity relationship diagrams are a widely used in software engineering. Using ERD software engineers can control the every aspect of database development. ER diagram can be used as guide for testing and communicating before the release of software product. ERD displays data as entities that are connected with connections that show the relationships between entities. There is some ERD notations used by data bases developers for representing the relationships between the data objects. ConceptDraw PRO and its ERD solution allow you to build ERD diagram of any notation.
