Entity Relationship Diagram Software Engineering
Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for data modeling, system design and illustrating the logical structure of databases. Introduced by Peter Chen the ER modeling technique is now successfully used in software development, when creating conceptual data model of an information system.
There are used three basic elements for ERDs construction: entities, attributes, relationships. Chen's notation for ERD assumes the use of rectangles to represent entities and diamonds to represent relationships between first-class objects. Another popular notation for ER diagrams is Crow's foot notation.
Professional ERD drawing is an essential software engineering method for database modeling. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram software engineering offers the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park.

There are several basic topologies including bus, star, point-to-point, ring and a hybrid. Two computers can form a fully connected network topology, and as the number of network nodes increases, the network diagram gets more complicated. This type of topology is also called a full mesh.
This is a visual example of a computer network built using a mesh topology. This diagram presents the schematic structure of the full mesh network topology. A common mesh network topology means that each network device is connected with several points in the network, so if the one node of the network goes down, it does not cause an issue with an operability of the entire computer network. In a full mesh network topology, every computer or device in the network is interconnected with each of the other devices in the network.

Wiring and circuit diagrams use special symbols recognized by everyone who uses the drawings. The symbols on the drawings show how components like resistors, capacitors, inductors, switches, lamps, acoustic devices, measuring devices and other electrical and electronic components are connected together.
26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.

No building project can exist without an electrical circuit map. It’s more convenient to develop electrical drawing with a proper software which would contain vector shapes and electrical symbols. This will help in the future if any problems appear.
This circuit diagram shows the scheme of a location of components and connections of the electrical circuit using a set of standard symbols. It can be use for graphical documentation of an electrical circuit components. There are many of different electric circuit symbols that can be used in a circuit diagram. Knowing how to read circuit diagrams is a useful skill not only for professionals, but for any person who can start creating his own small home electronic projects.

Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw DIAGRAM.

If you are just a beginner in drawing flowcharts, it may seem that a sheet of paper and a pen are just enough. However, at the time you would want to share your results, diagramming applications would suite you better. it’s very easy to create diagrams that way and to discover new kinds of flowcharts.
The huge collection of sample ConceptDraw diagrams, charts, illustrations and other types of business drawings includes a wide range of business themes. A huge number of graphic images of ConceptDraw documents is divides on business application areas according to business-oriented solutions for which they were made.Here is a short visual list of samples of flowcharts, process diagrams, UML models, management charts, computer network diagrams, maps, infographics, illustrations, etc. In short, each ConceptDraw solution is accompanied with at least ten samples representing some particular examples of the application of the given chart.

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams.
This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.
