ERD Symbols and Meanings

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.

Entity Relationship Diagram Symbols

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.
The vector stencils library "Local vehicular networking" contains 88 symbols for drawing the vehicular computer telecommunication network diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network.[1] A VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 metres of each other to connect and, in turn, create a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes. ...
Vehicular ad hocal networks are expected to implement wireless technologies such as dedicated short-range communications (DSRC) which is a type of Wi-Fi. Other candidate wireless technologies are cellular, satellite, and WiMAX. Vehicular ad hoc networks can be viewed as component of the intelligent transportation systems (ITS).
As promoted in ITS, vehicles communicate with each other via inter-vehicle communication (IVC) as well as with roadside base stations via roadside-to-vehicle communication (RVC)." [Vehicular ad hoc network. Wikipedia]
The example "Design elements - Local vehicular networking" is included in the Vehicular Networking solution from the Computer and Networks area of ConceptDraw Solution Park.

UML Class Diagram Generalization Example UML Diagrams

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Class Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample describes the use of the classes, the generalization associations between them, the multiplicity of associations and constraints. Provided UML diagram is one of the examples set that are part of Rapid UML solution.

Relationships Analysis

Relationships Analysis. Relations Diagram - factors analysis, factors relations. Create Relations Diagram with ConceptDraw DIAGRAM.
The Seven Management and Planning Tools is a tool for Interaction diagram drawing. This diagram identifies causal relationships. Determine what factors are causes and which factors are effects. Interaction diagram helps establish KPIs to monitor changes and the effectiveness of corrective actions in resolving the problem.

What is Entity-Relationship Diagram

Entity Relationship Diagram (ERD) is an acknowledged method to visualize the logical structure of databases. Using special symbols described in ERD notations you can depict a database of any complexity.
The vector graphic ER diagrams produced when using ConceptDraw ERD solution can be used in whitepapers, presentations, datasheets, posters, or any technical materials.

ConceptDraw DIAGRAM diagramming and vector drawing software gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram(ERD) solution from the Software Development area supplies the ConceptDraw DIAGRAM with icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.
