Entity-Relationship Diagram (ERD)

Entity-Relationship Diagram (ERD) solution extends ConceptDraw PRO software with templates, samples and libraries of vector stencils from drawing the ER-diagrams by Chen's and crow’s foot notations.

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 Build an Entity Relationship Diagram (ERD)

Entity Relationship Diagram Software

Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for illustrating the logical structure of databases. Professional ERD drawing is an essential software engineering method for database modeling. Use powerful tools of ConceptDraw PRO Entity Relationship Diagram Software extended with Entity-Relationship Diagram (ERD) Solution.

How to Create a Concept Map in ConceptDraw PRO

Graphical technique of knowledge representation in a form of structured networks of concepts (ideas) is called concept mapping. Concept network consists of shapes that represent concepts and connectors representing relationships between concepts. The difference between mind maps and concept maps is that a mind map has only one object depicting a main idea , while a concept map may have several. Concept mapping is used to structure ideas, to communicate complex system of knowledge, to help learning process, etc. ConceptDraw PRO allows you to draw concept maps using the Concept Map solution.
