Entity Relationship Diagram Symbols

Entity Relationship Diagram Symbols
The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style. The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM software.
The vector stencils library "Audio" contains 91 audio, sound and music icons. Use it to design your audio, video and multimedia illustrations, presentations, web pages and infographics with ConceptDraw PRO diagramming and vector drawing software.
"Digital audio refers to technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form. Following significant advances in digital audio technology during the 1970s, it rapidly replaced analog audio technology in most areas of sound production, sound engineering and telecommunications. Sound is converted to an analog electrical signal by a microphone, then an analog-to-digital converter (ADC), typically using pulse-code modulation, is used to convert it to a digital signal. A digital-to-analog converter performs the reverse process, converting a digital signal back into an analog signal, which can be converted to an audible sound by a loudspeaker. Digital audio systems may include compression, storage, processing and transmission components. Conversion to a digital format allows convenient manipulation, storage, transmission and retrieval of an audio signal." [Digital audio. Wikipedia]
The vector stencils library "Audio" is included in the Audio, Video, Media solution from the Illustration area of ConceptDraw Solution Park.

Local area network (LAN). Computer and Network Examples

Local area network (LAN) diagram
Local Area Network (LAN) is a network which consists of computers and peripheral devices connected each other and to the local domain server, and covers a little territory or small number of buildings, such as home, school, laboratory, office, etc. LAN serves for few hundreds of users. It includes many cables and wires, and demands to design previously a Network diagram. All local area network devices can use the shared printers and disk storage. ConceptDraw DIAGRAM is a perfect network diagramming software with examples of LAN Diagrams, templates and predesigned vector objects.

Pyramid Diagram

Pyramid diagram is a chart used to visualize the data in a hierarchical (pyramid-like) structure and depict the foundation-based relationships. Pyramid diagram looks like a triangle divided by lines into several sections (layers) and can be oriented up or down, and represented in 2D or 3D view. 2D Pyramid diagrams are a great way to illustrate the hierarchical structure, 3D Pyramids are equally good to represent the class stratification and hierarchy. ConceptDraw DIAGRAM diagramming and vector drawing software with included Pyramid Diagrams solution from Marketing area of ConceptDraw Solution Park is a powerful application which contains templates and library of vector design elements for instantly drawing three level Pyramid model, four level and five level Triangle charts. All predesigned objects are easy for changing color style and resizing according to your needs, and ConceptDraw documents with Pyramid diagrams can be easy exported in various formats for further using in marketing presentations, for effective analyzing hierarchy levels and illustration your data and ideas.

Star Network Topology

Star is a basic computer network topology in which all nodes (computers and peripheral devices) of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Such network segment can function separately or as a part of complex network topology. The switch is a server, the peripherals are the clients. The large workload and functions of network management are entrusted on the central computer, all information exchange goes through it, so it must to be obligatory the most powerful. The star network topology is a simple topology for design and implementation. Its advantages are high performance, flexible administration capabilities, simplicity of adding additional nodes and search of faults, the fact that a failure of one workstation doesn't affect the work of entire network. But the failure of central hub will result the failure of whole network or network segment - it's the main disadvantage. Use the ConceptDraw DIAGRAM with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.

"A call centre or call center is a centralised office used for the purpose of receiving or transmitting a large volume of requests by telephone. An inbound call centre is operated by a company to administer incoming product support or information inquiries from consumers. Outbound call centers are operated for telemarketing, solicitation of charitable or political donations, debt collection and market research. In addition to a call centre, collective handling of letter, fax, live support software,social media and e-mail at one location is known as a contact centre.
A call centre is operated through an extensive open workspace for call centre agents, with work stations that include a computer for each agent, a telephone set or headset connected to a telecom switch, and one or more supervisor stations. It can be independently operated or networked with additional centres, often linked to a corporate computer network, including mainframes, microcomputers and LANs. Increasingly, the voice and data pathways into the centre are linked through a set of new technologies called computer telephony integration (CTI)." [Call centre. Wikipedia]
