Entity Relationship Diagram Examples

Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.
ConceptDraw gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram solution includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

The vector stencils library "Windows 8 apps" contains 40 shortcut icons of Windows 8 software applications.
Use this shortcut UI icon set to design graphic user interface (GUI) prototypes of your software apps for Windows 8.
"In computing, a file shortcut is a handle in a user interface that allows the user to find a file or resource located in a different directory or folder from the place where the shortcut is located.

Shortcuts are typically implemented as a small file containing a target URI or GUID to an object, or the name of a target program file that the shortcut represents. The shortcut might additionally specify parameters to be passed to the target program when it is run. Each shortcut can have its own icon. Shortcuts are very commonly placed on a desktop, in an application launcher panel such as the Microsoft Windows Start menu, or in the main menu of a desktop environment. ...
File shortcuts (also known as shell links) were introduced in Windows 95. Microsoft Windows uses .lnk as the filename extension for shortcuts to local files, and .URL for shortcuts to remote files, like web pages. Commonly referred to as "shortcuts" or "link files", both are displayed with a curled arrow overlay icon by default, and no filename extension. ...
Shortcut files can be used to launch programs in minimized or maximized window states if the program supports it. ...
Beginning with Windows 7, some shortcuts also store Application User Model IDs (AppUserModelIDs). Instead of the target command line, AppUserModelIDs may directly be used to launch applications. Shortcuts with AppUserModelIDs are used by some desktop programs and all WinRT Modern apps for launching." [File shortcut. Wikipedia]
The shortcut icons example "Windows 8 apps - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Windows 8 User Interface solution from the Software Development area of ConceptDraw Solution Park.

Local area network (LAN). Computer and Network Examples

A local area network (LAN) is a devices network that connect with each other in the scope of a home, school, laboratory, or office. Usually, a LAN comprise computers and peripheral devices linked to a local domain server. All network appliances can use a shared printers or disk storage. A local area network serve for many hundreds of users. Typically, LAN includes many wires and cables that demand a previously designed network diagram. They are used by IT professionals to visually document the LANs physical structure and arrangement.
ConceptDraw - Perfect Network Diagramming Software with examples of LAN Diagrams. ConceptDraw Network Diagram is ideal for network engineers and network designers who need to draw Local Area Network diagrams.

How To Make a Crow's Foot ER Diagram

The Crow's Foot ERD notation is often used in software engineering and database design. The originator of Crow’s Foot notation was Gordon Everest, who offered the idea of how to visually represent the different types of relationships that can exist between objects in an entity relationship diagram (ERD). The Crow’s Foot notation is often used in ER models to how a particular table data can reference data in other tables within a database. The free Crow's Foot Notation solution for ConceptDraw PRO offers a complete vector stencil library containing full standardized symbols of Crow's Foot notation.

How To Make Chen ER Diagram

The Chen ERD notation model is a popular standard and is widely used worldwide in database and software design. The entity-relationship model proposed by Dr. Chen is constructed using a natural view of how the real world comprises entities and the relationships that exist with these identified entities. It was designed to leverage the advantages of the three entity-data models (network model, relationship model, entity model). The free Chen Notation solution for ConceptDraw PRO provides vector stencil libraries with full standardized Chen notation included.

The vector stencils library "Network hardware" contains 27 clipart images and symbols of network equipment for drawing computer network diagrams.
"Networking hardware may also be known as network equipment or computer networking devices. Units which are the last receiver or generate data are called hosts or data terminal equipment.
All these terms refer to devices facilitating the use of a computer network. Specifically, they mediate data in a computer network. ...
Typically, networking hardware includes gateways, routers, network bridges, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, modems, ISDN terminal adapters, line drivers, wireless access points, networking cables and other related hardware.
The most common kind of networking hardware today is a copper-based Ethernet adapter because of its standard inclusion on most modern computer systems. Wireless networking has, however, become increasingly popular, especially for portable and handheld devices.
Other hardware prevalent in computer networking includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery.
Taking a wider view, mobile phones, PDAs and even modern coffee machines may also be considered networking hardware. As technology advances and IP-based networks are integrated into building infrastructure and household utilities, network hardware will becomes an ambiguous term owing to the vastly increasing number of "network capable" endpoints."
