Entity-Relationship Diagram (ERD)

Entity-Relationship Diagram (ERD)

This solution extends ConceptDraw DIAGRAM software with the ability to describe a database using the Entity-Relationship model.

This solution includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

The vector graphic diagrams produced when using this solution can be used in your whitepapers, presentations, datasheets, posters or any technical material.


Design Elements

2 libraries, 45 objects included in Entity-Relationship Diagram (ERD).

Examples

There are a few samples that you see on this page which were created in the ConceptDraw DIAGRAM application by using the Entity-Relationship Diagram (ERD) solution. Some of the solution's capabilities as well as the professional results which you can achieve are all demonstrated here on this page.

All source documents are vector graphic documents which are always available for modifying, reviewing and/or converting to many different formats, such as MS PowerPoint, PDF file, MS Visio, and many other graphic ones from the ConceptDraw Solution Park or ConceptDraw STORE. The Entity-Relationship Diagram (ERD) solution is available to all ConceptDraw DIAGRAM users to get installed and used while working in the ConceptDraw DIAGRAM diagramming and drawing software.

Example 1: Entity-Relationship Diagram Using Chen's Notation

This diagram was created in ConceptDraw DIAGRAM using the Chen ERD library from the Entity-Relationship Diagram (ERD) solution. An experienced user spent 20 minutes creating this sample.

This sample diagram using the Entity-Relationship Diagram (ERD) Solution shows the type of icons and graphics you can use to develop a model of a database of arbitrary complexity according to Chen's notation.

using ConceptDraw DIAGRAM software enhanced with ConceptDraw ERD solution.

Example 2: Entity-Relationship Diagram Using Crow's Foot Notation

This diagram was created in ConceptDraw DIAGRAM using the Crows Foot ERD library from the Entity-Relationship Diagram (ERD) solution. An experienced user spent 20 minutes creating this sample.

This sample diagram using the Entity-Relationship Diagram (ERD) Solution and shows the type of icons and graphics you can use to develop a model of a database of arbitrary complexity using Crow's Foot notation.

This diagram example was redrawn from https://www2.cs.uregina.ca/~bernatja/crowsfoot.html using ConceptDraw DIAGRAM software enhanced with ConceptDraw ERD solution.

Inside

What I Need to Get Started

Both ConceptDraw DIAGRAM diagramming and drawing software and the Entity-Relationship Diagram (ERD) solution can help creating the you need. The Entity-Relationship Diagram (ERD) solution can be found in the Universal Diagramming area of ConceptDraw STORE application that can be downloaded from this site. Make sure that both ConceptDraw DIAGRAM and ConceptDraw STORE applications are installed on your computer before you get started.

How to install
