Entity-Relationship Diagram (ERD)

This solution extends ConceptDraw PRO v9.4 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

The samples you see on this page were created in ConceptDraw PRO using the Entity-Relationship Diagram (ERD) solution, and demonstrate some of the solution's capabilities and the results you can achieve.

All source documents are vector graphic documents. They are available for reviewing, modifying, and converting to a variety of available formats (PDF file, PowerPoint Presentation, image, or MS Visio XML) from the Template Gallery of ConceptDraw PRO, for all users who have installed the Entity-Relationship Diagram (ERD) solution.

Example 1: Entity-Relationship Diagram using Chen's notation

This diagram was created in ConceptDraw PRO 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.

Example 2: Entity-Relationship Diagram using Crow's Foot notation

This diagram was created in ConceptDraw PRO 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.
