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.

What is ConceptDraw PRO

Types of Flowcharts

A Flowchart is a graphical representation of process, algorithm, workflow or step-by-step solution of the problem. It shows the steps as boxes of various kinds and connects them by arrows in a defined order depicting a flow. There are twelve main Flowchart types: Basic Flowchart, Business Process Modeling Diagram (BPMN), Cross Functional Flowchart, Data Flow Diagram (DFD), IDEF (Integrated DEFinition) Flowchart, Event-driven Process Chain (EPC) Diagram, Influence Diagram (ID), Swimlane Flowchart, Process Flow Diagram (PFD), Specification and Description Language (SDL) Diagram, Value Stream Mapping, Workflow Diagram. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design a Flowchart of any of these types. This solution offers a lot of special predesigned vector symbols for each of these widely used notations. They will make the drawing process of Flowcharts much easier than ever.

Metropolitan area networks (MAN). Computer and Network Examples

A Metropolitan Area Network (MAN) is a great computer network located on the large geographical area or region. It is a network bigger than Local Area Network (LAN), but territorially smaller than Wide Area Network (WAN), its diameter usually ranges from 5 to 50 kilometers. MAN usually includes several buildings or even the whole city (metropolis). It is based on high data rate compounds using the fiber channels and other digital data transmission channels. MAN includes a lot of communicating devices, for its construction are used multiple routers, switches and hubs. MAN can combine together several Local Area Networks or Campus Area Networks located in different buildings within a city and provides the Internet connectivity for them. Solutions included to Computer and Networks Area for ConceptDraw Solution Park are the real godsend for those who want design Computer Network Diagrams, and among others the Metropolitan Area Network Diagrams. They offer the libraries with ready-to-use vector design elements, professional-looking examples, samples and templates.

Design elements - Audio and video connectors

The vector stencils library "Audio and video connectors" contains 94 symbols of audio and video connectors (TRS, TS, XLR, microphone, headphone, TOSLINK, DVI, VGA, DFP, S-Video, RCA, display port, HDMI, Thunderbolt, coaxial TV, F connector, MIDI) and device silhouettes.
Use these jacks and plugs clipart icons for drawing hook up diagrams.
"Audio connectors and video connectors are electrical connectors (or optical connectors) for carrying audio signal and video signal, of either analog or digital format. Analog A/ V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise." [Audio and video connector. Wikipedia]
"The existence of many different audio and video standards necessitates the definition of hardware interfaces, which define the physical characteristics of the connections between electrical equipment. This includes the types and numbers of wires required along with the strength and frequency of the signal. It also includes the physical design of the plugs and sockets.
An interface may define a connector that is used only by that interface (e.g., DVI) or may define a connector that is also used by another interface; for example, RCA connectors are defined both by the composite video and component video interfaces.
Audio connectors and video connectors are electrical connectors (or optical connectors) for carrying audio signal and video signal, of either analog or digital format. Analog A/ V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise.
Since both analog and digital signals are used with some styles of connectors, knowledge of the interface used is necessary for a successful transfer of signals. Some interface types use only a distinctive connector or family of connectors, to ensure compatibility. Especially with analog interfaces, physically interchangeable connectors may not carry compatible signals.
Some of these connectors, and other types of connectors, are also used at radio frequency (RF) to connect a radio or television receiver to an antenna or to a cable system..." [Audio and video interfaces and connectors. Wikipedia]
The clipart icons example "Design elements - Audio and video connectors" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Audio and Video Connectors solution from the Engineering area of ConceptDraw Solution Park.

Bubble diagrams in Landscape Design with ConceptDraw PRO

Bubble Diagrams are the charts with a bubble presentation of data with obligatory consideration of bubble's sizes. They are analogs of Mind Maps and find their application at many fields, and even in landscape design. At this case the bubbles are applied to illustrate the arrangement of different areas of future landscape design, such as lawns, flowerbeds, playgrounds, pools, recreation areas, etc. Bubble Diagram helps to see instantly the whole project, it is easy for design and quite informative, in most cases it reflects all needed information. Often Bubble Diagram is used as a draft for the future landscape project, on the first stage of its design, and in case of approval of chosen design concept is created advanced detailed landscape plan with specification of plants and used materials. Creation of Bubble Diagrams for landscape in ConceptDraw PRO software is an easy task thanks to the Bubble Diagrams solution from "Diagrams" area. You can use the ready scanned location plan as the base or create it easy using the special ConceptDraw libraries and templates.
