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.

How to Build an Entity Relationship Diagram (ERD)

Notation & Symbols for ERD

The ER diagram is constructed from the specific ERD graphic elements. There are used 2 types of ERD notations: Chen and Crow's Foot.
A complete set of work flow shapes, notation & symbols for ERD, entity relationship stencils, included in Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software, makes drawing diagrams based on ERD notation as smooth as possible.

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.

Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for data modeling, system design and illustrating the logical structure of databases.
Professional ERD drawing is an essential software engineering method for database modeling. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram Software Engineering offers the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park.

Components of ER Diagram

ConceptDraw gives the ability to draw ER diagram (ERD) for visual describing database using the entity relationship symbols, work flow shapes, entity relationship stencils. Entity-Relationship model making possibility to describe a database using the components of ER Diagram in which in the tables data can be the point to data in other tables - for instance, your entry in the database could point to several entries.

ER Diagram Styles

When creating ER diagrams, you can apply different color ER diagram styles and also notation styles. ConceptDraw DIAGRAM enhanced with Entity-Relationship Diagram (ERD) Solution gives the ability to draw visual and attractive ER Diagrams using the style icons from Crow’s Foot notation and Chen's notation professionally designed and offered by ERD Chen's Notation and ERD Crow’s Foot Notation libraries.

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.

ER Diagram Programs for Mac

ConceptDraw DIAGRAM compatible Mac OS X software extended with powerful Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park is one of the famous ER Diagram Programs for Mac. It gives the perfect ability to draw ER diagrams for visually describing databases with Chen's and Crow's Foot notation icons.

Entity-Relationship Diagram (ERD)

An Entity-Relationship Diagram (ERD) is a visual presentation of entities and relationships. That type of diagrams is often used in the semi-structured or unstructured data in databases and information systems. At first glance ERD is similar to a flowch

Entity Relationship Software

Entity Relationship Diagrams (ERD) illustrate the logical structure of databases.
The vector graphic diagrams produced when using the ConceptDraw ERD solution can be used in whitepapers, presentations, datasheets, posters, or any technical materials.
It is convenient to design ER Diagrams using ConceptDraw DIAGRAM software. ConceptDraw DIAGRAM extended with the Entity-Relationship Diagram (ERD) solution supports Chen's and Crow’s Foot notations that are often used to describe database structure.

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.

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.

UML Class Diagram Notation

When it comes to system construction, a class diagram is the most widely used diagram. UML Class Diagrams is a type of static structure diagram that is used for general conceptual modeling of the systematics of the application. Such a diagram would illustrate the object-oriented view of a system. The object orientation of a system is indicated by a class diagram. It describes the structure of a system by showing the general issues,classes of a system, attributes, operations, interfaces, inheritance, and the relationships between them.
