Entity Relationship Diagram Examples

Create 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 DIAGRAM diagramming and vector drawing software gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram(ERD) solution from the Software Development area supplies the ConceptDraw DIAGRAM with icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

This AWS architecture diagram example shows the deployment of Drupal architecture on the Amazon Web Services Cloud.
This AWS architecture sample was designed on the base of the diagram "Drupal on AWS" from the Amazon Web Services website. [aws.amazon.com/ ru/ quickstart/ architecture/ drupal/ ]
"This reference architecture provides a set of YAML templates for deploying Drupal on AWS using Amazon Virtual Private Cloud (Amazon VPC), Amazon Elastic Compute Cloud (Amazon EC2), Auto Scaling, Elastic Load Balancing (Application Load Balancer), Amazon Relational Database Service (Amazon RDS), Amazon ElastiCache, Amazon Elastic File System (Amazon EFS), Amazon CloudFront, Amazon Route 53, Amazon Certificate Manager (Amazon ACM) with AWS CloudFormation." [github.com/ aws-samples/ aws-refarch-drupal]
The Amazon Web Services diagram example "Drupal Hosting on AWS" was designed using ConceptDraw PRO software extended with AWS Architecture Diagrams solution from Computer and Networks area of ConceptDraw Solution Park.

Campus Area Networks (CAN). Computer and Network Examples

Campus Area Networks (CAN). <br>Computer and Network Examples *

A campus network provides wireless access to the Internet or LAN to users located in two or more buildings or in the open space surrounding those buildings. A campus network is usually set in the campus of a university, but the same kind of planning and design can be applied for other purposes. For example, the campus network can used for an office or industrial park, in a public place like a supermarket with an entertainment center, even on a farm. Another form of temporary campus network can exist during special events such as music festivals or rallies.
The elementary campus networks arise spontaneously: the radio signals from the access points, which provide network inside the building are not limited to its walls, so any user in the backyard can also get wireless network access. The larger and more complex campus network may have additional access points in places specially chosen for serving clients, i.e., on the lawn in front of the college or in a coffee shop around the corner.

Diagram of a Basic Computer Network. Computer Network Diagram Example

What is a computer network? This is a set of devices and systems that are connected to each other (logically or physically) and communicate with each other. This could include servers, computers, phones, routers, and so on. The size of this network can reach the size of the Internet, and can consist of only two devices connected by a cable.
This sample shows the connection scheme of the home WLAN equipment to the Internet.

Entity Relationship Diagram Examples

The vector stencils library "Active Directory" contains 20 symbols of Active Directory elements for drawing AD network diagrams. It helps network and system administrators to visualize Microsoft Windows Active Directory structures for network design, installation and maintainance.
"An Active Directory structure is an arrangement of information about objects. The objects fall into two broad categories: resources (e.g., printers) and security principals (user or computer accounts and groups). Security principals are assigned unique security identifiers (SIDs).
Each object represents a single entity - whether a user, a computer, a printer, or a group - and its attributes. Certain objects can contain other objects. An object is uniquely identified by its name and has a set of attributes - the characteristics and information that the object represents - defined by a schema, which also determines the kinds of objects that can be stored in Active Directory.
The schema object lets administrators extend or modify the schema when necessary. However, because each schema object is integral to the definition of Active Directory objects, deactivating or changing these objects can fundamentally change or disrupt a deployment. Schema changes automatically propagate throughout the system. Once created, an object can only be deactivated - not deleted. Changing the schema usually requires planning. Sites are implemented as a set of well-connected subnets." [Active Directory. Wikipedia]
The AD symbols example "Active Directory - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Active Directory Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.
