How To Make a Crow's Foot ER Diagram

How To Make a Crow's Foot ER Diagram
The Crow's Foot ERD notation is often used in software engineering and database design. The originator of Crow’s Foot notation was Gordon Everest, who offered the idea of how to visually represent the different types of relationships that can exist between objects in an entity relationship diagram (ERD). The Crow’s Foot notation is often used in ER models to how a particular table data can reference data in other tables within a database. The free Crow's Foot Notation solution for ConceptDraw DIAGRAM offers a complete vector stencil library containing full standardized symbols of Crow's Foot notation.

How To Make Chen ER Diagram

How To Make Chen ER Diagram
The Chen ERD notation model is a popular standard and is widely used worldwide in database and software design. The entity-relationship model proposed by Dr. Chen is constructed using a natural view of how the real world comprises entities and the relationships that exist with these identified entities. It was designed to leverage the advantages of the three entity-data models (network model, relationship model, entity model). The free Chen Notation solution for ConceptDraw DIAGRAM provides vector stencil libraries with full standardized Chen notation included.
