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)

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.

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.

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.

Cisco Network Topology. <br>Cisco icons, shapes, stencils and symbols *

The Cisco Network Diagrams solution uses Cisco network symbols and Cisco icons to visualize computer networks. Cisco Network Topology is the arrangement of the Cisco symbols that display scheme of computer network.
Any Cisco equipment on the network are named like node. Network diagram topology commonly designed within connected nodes. Cisco icons are worldwide acknowledged and mainly established as standard icons for network diagrams. You may use them loosely, but you may not rework them.
The Cisco Network Diagram shows how signals act on the networked devices, or how data routes on the network from one device to the other. There are number of physical network typologies that engineers use while constructing computer networks.
