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.
Wiring Diagrams with ConceptDraw DIAGRAM
A wiring diagram is a comprehensive diagram of each electrical circuit system showing all the connectors, wiring, terminal boards, signal connections (buses) between the devices and electrical or electronic components of the circuit. It also identifies the wires by wire numbers or colour coding. Wiring diagrams are necessary to troubleshoot and fix electrical or electronic circuits.Electrical Drawing Software and Electrical Symbols
ConceptDraw DIAGRAM is a powerful software for creating professional looking electrical circuits quick and easy. For this purpose you can use the Electrical Engineering solution from the "Engineering" area of ConceptDraw Solution Park.Electrical Drawing Software provides the 26 stencils libraries of ready-to-use predesigned vector electrical symbols, templates and samples that make your electrical drawing quick, easy and effective.
The vector stencils library "Transport map" contains 96 pictograms for drawing transport maps.
Use it in your spatial infographics for visual representation of transport schemes and plans as metro maps in the ConceptDraw PRO diagramming and vector drawing software extended with the Spatial Infographics solution from the area "What is Infographics" of ConceptDraw Solution Park.
