ERD Symbols and Meanings

Entity Relationship Diagram Symbols and Meaning - crow's foot notation
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 PRO 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.

Basic Flowchart Symbols and Meaning

Flowchart Symbols and Meaning, workflow diagram symbols, process flow diagram symbols
Flowcharts are the best for visually representation the business processes and the flow of a custom-order process through various departments within an organization. ConceptDraw PRO diagramming and vector drawing software extended with Flowcharts solution offers the full set of predesigned basic flowchart symbols which are gathered at two libraries: Flowchart and Flowcharts Rapid Draw. Among them are: process, terminator, decision, data, document, display, manual loop, and many other specific symbols. The meaning for each symbol offered by ConceptDraw gives the presentation about their proposed use in professional Flowcharts for business and technical processes, software algorithms, well-developed structures of web sites, Workflow diagrams, Process flow diagram and correlation in developing on-line instructional projects or business process system. Use of ready flow chart symbols in diagrams is incredibly useful - you need simply drag desired from the libraries to your document and arrange them in required order. There are a few serious alternatives to Visio for Mac, one of them is ConceptDraw PRO. It is one of the main contender with the most similar features and capabilities.

The vector stencils library "Qualifying" contains 56 qualifying symbols of radiation, polarity, phase, windings, wire, ground, connection, connector, coaxial, electret.
Use these signs to annotate or specify characteristics of objects in electrical drawings, electronic schematics, circuit diagrams, electromechanical drawings, and wiring diagrams, cabling layout diagrams.
"An electrical drawing, is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project. Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".
A complete set of working drawings for the average electrical system in large projects usually consists of:
(1) A plot plan showing the building's location and outside electrical wiring.
(2) Floor plans showing the location of electrical systems on every floor.
(3) Power-riser diagrams showing panel boards.
(4) Control wiring diagrams.
(5) Schedules and other information in combination with construction drawings.
Electrical drafters prepare wiring and layout diagrams used by workers who erect, install, and repair electrical equipment and wiring in communication centers, power plants, electrical distribution systems, and buildings." [Electrical drawing. Wikipedia]
The signs example "Design elements - Qualifying" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Electrical Engineering solution from the Engineering area of ConceptDraw Solution Park.

How To Create CCTV Network Diagram

CCTV Network Diagram - Home CCTV system
Closed-circuit television (CCTV) uses cameras and monitors to carry out video surveillance. Unlike broadcast television this system has only local signal. It is a feature of almost every video camera, yet CCTV is mainly a system for visual control of certain areas such as banks, airports, supermarkets, and other places for security reasons. Developing and installing CCTV system is a time-consuming process. It also requires certain knowledge and skills. ConceptDraw is a solution of setting video cameras rationally. You can achieve two aims at once: CCTV Design Tool saves your time and your money and helps you make professional video surveillance system.
