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.

Entity-Relationship Diagram (ERD)
Entity-Relationship Diagram (ERD) solution extends ConceptDraw DIAGRAM software with templates, samples and libraries of vector stencils from drawing the ER-diagrams by Chen's and crow’s foot notations.
ConceptDraw DIAGRAM Compatibility with MS Visio
For those who are migrating from MS Visio to ConceptDraw DIAGRAM, or for those who have colleagues and clients who use Visio, ConceptDraw DIAGRAM is compatible with MS Visio.VSDX formatted files.VSDX is Visio’s open XML file format, and it can be easily imported and exported by ConceptDraw DIAGRAM.- Design elements - ERD (crow's foot notation) | Entity Relationship ...
