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.

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.
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.

Entity Relationship Diagram Symbols

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.
ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM.

Introduction to Cloud Computing Architecture

The best way to visualize the introduction to Cloud computing architecture is to create diagrams and schematics representing what is a cloud computing and how it works. For their design, we recommend to use a powerful ConceptDraw DIAGRAM diagramming and vector drawing software supplied with Cloud Computing Diagrams solution from the Computers and Network area of ConceptDraw Solution Park

UML Use Case Diagram Example. Social Networking Sites Project

UML Diagrams Social Networking Sites Project. This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the Facebook Socio-health system and is used at the projection and creating of the social networking sites.

Sequence Diagram for Cloud Computing

One of the ways effectively visualize what is a Cloud computing or Cloud computing architecture, is to create the Sequence diagram for Cloud computing. The ConceptDraw DIAGRAM diagramming and vector drawing software enhanced with Cloud Computing Diagrams solution from the Computers and Network area of ConceptDraw Solution Park will help you design all desired types of diagrams related with cloud computing.

Business Process Modeling Notation Template

Create business process diagrams (BPMN 2.0.) with ConceptDraw using professional looking templates. ConceptDraw is business process improvement tools.

What is Cloud Computing

What is Cloud Computing? The Cloud computing is a widely used and highly demanded utility in the modern world thanks to its high computing power, performance, scalability and accessibility, and at the same time low cost of services. The ConceptDraw DIAGRAM diagramming and vector drawing software provides an easy and effective Cloud Computing Diagrams solution from the Computers and Network area of ConceptDraw Solution Park for making professional looking Cloud Computing and Cloud Computing Architecture Diagrams.

Software and Database Design with ConceptDraw DIAGRAM

ConceptDraw DIAGRAM is a perfect tool for designing and planning tasks such as:
UML diagramming; designing and prototyping Graphical User Interface (GUI); flowcharts, data flow diagrams; database and ERD diagramming (Chen ERD, Database Model diagram, Express-G, Martin ERD, ORM Diagrams and more); SSADM diagrams, Booch diagrams, Nassi-Shneiderman diagrams with special flowchart symbols.

SSADM Diagram

The vector stencils library SSADM from the solution Systems engineering contains specific symbols of SSADM diagrams for ConceptDraw DIAGRAM diagramming and vector drawing software. The Systems engineering solution is contained in Software Development area of ConceptDraw Solution Park.
The example below illustrates the waterfall model used in SSADM. This model involves 5 stages of developing a product such as requirements specification and its' analysis, design, coding and testing.
