Entity Relationship Diagrams

“In software engineering, an entity–relationship model (ER model) is a data model for describing the data or information aspects of a business domain or its process requirements, in an abstract way that lends itself to ultimately being implemented in a database such as a relational database. The main components of ER models are entities (things) and the relationships that can exist among them, and databases.” [from Wikipedia]

The Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park extends ConceptDraw DIAGRAM ector graphics and diagramming software with the ability of drawing the Entity Relationship Diagrams for visually describing the databases with Crow’s Foot and Chen's notation icons.

No matter which way you choose - use the predesigned templates and samples, or design Entity Relationship Diagrams de novo, you will be useful to use the vector objects provided by libraries of Entity-Relationship Diagram (ERD) solution.

Sample 3. Entity Relationship Diagrams - ER Model Diagram

This sample was created in ConceptDraw DIAGRAM using the vector objects from the ERD Crow's Foot Notation library of Entity-Relationship Diagram (ERD) Solution and illustrates the Entity Relationship Model Diagram. An experienced user spent 15 minutes creating this sample.

All source documents are vector graphic documents. They are available for reviewing, modifying, or converting to a variety of formats (PDF file, MS PowerPoint, MS Visio, and many other graphic formats) from the ConceptDraw STORE. The Entity-Relationship Diagram (ERD) Solution is available for all ConceptDraw DIAGRAM or later users.
