ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates. ConceptDraw Pro is a great alternative to Visio for Mac users as it offers more features and can easily handle the most demanding professional needs.

Wiring Diagrams with ConceptDraw DIAGRAM

A Wiring Diagram is a comprehensive schematic that depicts the electrical circuit system, shows all the connectors, wiring, signal connections (buses), terminal boards between electrical or electronic components and devices of the circuit. Wiring Diagram illustrates how the components are connected electrically and identifies the wires by colour coding or wire numbers. These diagrams are necessary and obligatory for identifying and fixing faults of electrical or electronic circuits, and their elimination. For designing Wiring Diagrams are used the standardized symbols representing electrical components and devices. ConceptDraw Solution Park offers the Electrical Engineering solution from the Engineering area with 26 libraries of graphics design elements and electrical schematic symbols for easy drawing various Wiring Diagrams, Electrical Circuit and Wiring Blueprints, Electrical and Telecom schematics of any complexity, Electrical Engineering Diagrams, Power Systems Diagrams, Repair Diagrams, Maintenance Schemes, etc. in ConceptDraw DIAGRAM software.

Electrical Drawing Software and Electrical Symbols

Any electrical device could not be created without electrical diagram, wiring also cannot be laid without pre-designed and approved scheme or plan. Electrical drawing is a type of technical drawing that depicts scheme of some electrical device and includes the information about power, lighting, etc. Electrical plan designed for architectural or engineering project visually displays location of electrical devices and connections. ConceptDraw DIAGRAM is ideal electrical software for construction professional-looking Electrical Circuits, Electrical Schematics, Electrical Layouts, Electrical Wiring, Automotive Wiring, Cabling Layout Diagrams, Circuits and Logic Schematics, Logic Gate Diagrams, Digital Circuits, Parallel Circuits, Blue Prints with help of 926 standard electrical symbols offered by 26 libraries of Electrical Engineering solution from the Engineering area for ConceptDraw DIAGRAM. It makes drawing Electrical diagrams very easy even for beginners, and also extends your work with various export methods.
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.
