ERD, entity-relationship diagram, ER-diagram, Chen Notation
The Chen Notation solution extends ConceptDraw DIAGRAM software with rich collection of ERD samples and selection of special Chen's notation icons for effective database design, data modeling, and visual representation of relationships between the entities on the ER diagrams designed with Chen notation.

Chen ERD Diagram

The vector stencils library Chen ERD from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Chen ERD notation including entity symbols and relationship symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Entity-Relationship Diagrams (ERD) solution is contained in the Software Development area of ConceptDraw Solution Park.

Entity Relationship Diagram Symbols

Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.
ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw 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.

Design Element: Chen for Entity Relationship Diagram - ERD

Entity-relationship diagrams (ERDs) are intended for the development of data models and provide a standard method for determining data and relationships between them. The first notation for ERD was introduced by Chen. Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park provides the libraries with predesigned set of ERD diagram design element Chen corresponding entities and relationships.

Entity Relationship Diagram - ERD - Software for Design Chen ER Diagrams

The Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park extends ConceptDraw DIAGRAM vector graphics and diagramming software with the ability to describe a database using the Entity-Relationship (Chen) model. Use it for design your ERDs and verify that ConceptDraw DIAGRAM offers the best ERD diagrams software tools for design element Chen notation.

Design Element: Crows Foot for Entity Relationship Diagram - ERD

Creating an ERD requires choosing a specific set of notations that best serve the specific database being designed. ConceptDraw DIAGRAM software extended with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park allows you to draw ER diagrams for depicting a database using the ERD diagram design element Crow's Foot - Crow′s Foot notation icons.

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.

ConceptDraw DIAGRAM ER Diagram Tool

ER-diagram is a tool used for database modeling which allows to determine data and relationships among the data. These diagrams help to detail data storages and to document all the properties of designed system. ER-diagram contains entities, attributes of the entities and the relationships between them. Chen’s notation and Crow’s foot notation are commonly used to represent elements in ER-model. To create such diagram you should use specific software, such as Entity-Relationship Diagram solution for ConceptDraw DIAGRAM.
ConceptDraw ER Diagram Tool works across any platform, meaning you never have to worry about compatibility again. ConceptDraw DIAGRAM allows you to make Entity-Relationship Diagram (ERD) on PC or macOS operating systems.

Entity Relationship Diagram Examples

Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.
ConceptDraw gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram solution includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.
