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.

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 Diagram (ERD) with ConceptDraw PRO

erd diagram example, er-diagram design software

Entity-Relationship Diagram (ERD) serves for detailed description of structures and databases. An ERD represents a diagram made up mainly of rectangular blocks (for entities, or data) linked with relationships. The links between the blocks describe relations between these entities. There are three types of relationships: one-to-one,
one-to-many, many-to-many.

How to Create an ERD Diagram

Entity-Relationship Diagram (ERD) using Chen's notation

ERD (entity relationship diagram) is used to show the logical structure of databases. It represents the interrelationships between components of database (entities). Entity relationship diagrams are a widely used in software engineering. Using ERD software engineers can control the every aspect of database development. ER diagram can be used as guide for testing and communicating before the release of software product. ERD displays data as entities that are connected with connections that show the relationships between entities. There is some ERD notations used by data bases developers for representing the relationships between the data objects. ConceptDraw PRO and its ERD solution allow you to build ERD diagram of any notation.

ER Diagram for Cloud Computing

The entity–relationship (ER) model is a data model that lets graphically represent the information system and depict the relationships between people, objects, concepts, places, and events within a given system. It is also convenient to use the ER Diagram for Cloud computing representation and description the Cloud computing architecture, design them with pleasure using the extensive tools of the Cloud Computing Diagrams solution from the Computers and Network area of ConceptDraw Solution Park.
