entity-relationship diagram, ER-diagram, database ERD Entity-Relationship Diagram (ERD)

entity-relationship diagram, ER-diagram, database 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.
"In software engineering, an entity–relationship model (ER model) is a data model for describing a database in an abstract way. ...
Crow's Foot notation is used in Barker's Notation, 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." [Entity–relationship model. Wikipedia]
This ERD example was redesigned using the ConceptDraw PRO diagramming and vector drawing software from the educational data base model. [www2.cs.uregina.ca/ ~bernatja/ crowsfoot.html]
The example "Entity-relationship diagram (Crow's foot notation)" is included in the Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park.
