TEN RELATED HOW TO's:
It is very difficult to get into database model idea without any examples. To create one, you can use Chen’s notation for Entity Relationship Diagrams (ERD) and try to see all the peculiarities yourself. This notation describes entities and relations as basic geometric shapes like rectangles and diamonds.
Chen notation for Entity-relationship diagrams is used for designing relational databases. It depicts the database entities as a set of subjects. For example events, people, ideas, etc. All entities has common characteristics (attributes). Any object of the system is identified as the sole and unique. The name of entity should indicate the class or type of the the whole object, not a given example. The connection commonly represents a relationship between entities. Conceptdraw Entity-Relationship Diagrams (ERD) solution provides the libraries with ready-to-use ERD element fitting Chen's notation objects and relationships.

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology.
There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.

The Cause and Effect diagram introduced by Kaoru Ishikawa in 1968 is a method for analyzing process dispersion. It can help you to dive into a problem and find an effective solution, identify and represent the possible causes for an effect, analyze the complex business problems and successfully solve them.
You can design your Cause and Effect diagram on a paper, but more effective way is to use specific software - ConceptDraw DIAGRAM is a powerful Cause and Effect Diagram Software. It helps you create Cause and Effect diagram known also as Fishbone diagram or Ishikawa diagram from templates and examples.

It is important to have an electrical circuits scheme, when you plan a renovation or move to a new apartment. You have to arrange interior according to that plan, and it’s trouble-free to create wiring diagrams with ConceptDraw DIAGRAM , furthermore, this software has all the features needed to create an interior plan as well. So, get inspired by tons of examples included to ConceptDraw DIAGRAM solutions, and start your diagramming experience!
A wiring diagrams, that are represented on this drawing was created to depict the components of the electrical circuit schemes. These diagrams are created to depict the information about circuit arrangements and connections. Wiring diagrams, in contrast to physical drawings, use standard symbol's notation to depict different circuit devices and connections. That is why, wiring diagrams are applied to discover and repair electrical and electronic circuits. The vector graphic objects provided by ConceptDraw Electrical Engineering solution can help any specialist in electric engineering to design electrical schemes, circuit and wiring plans, power systems charts, and Maintenance and Repair diagrams.

In general, you can use any icons to represent network equipment on a diagram. However, there are some icons, for instance, Cisco icons, shapes, stencils and symbols, that are recognizable worldwide. Using those icons you can create Cisco network topology diagrams in minutes and share them anywhere.
The icons depicting Cisco network equipment are recognized and generally applied as standard images for designing network diagrams. They are free to used , but can not be reworked. Cisco network diagrams are created to depict how signals processed on the network equipment and end-user computers and how data transfer through LAN or WLAN between nodes. The vector graphic library of ConceptDraw CISCO Network Diagrams solution includes about 90 icons of Cisco network equipment for designing computer network diagrams with ConceptDraw DIAGRAM.
