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.

Data Modeling with Entity Relationship Diagram

Data modeling is actively applied in analysis and uses wide set of methods for description the data requirements in a system. One of the most popular and well-known is the ERD method of database modeling.
The best ERD tool for the Mac and Windows is ConceptDraw DIAGRAM software extended with the Entity-Relationship Diagram (ERD) solution from the Software Development Area for ConceptDraw Solution Park, which is sharpened for professional ERD drawing and data modeling with Entity Relationship Diagram.

Entity Relationship Software

Entity Relationship Diagrams (ERD) illustrate the logical structure of databases.
The vector graphic diagrams produced when using the ConceptDraw ERD solution can be used in whitepapers, presentations, datasheets, posters, or any technical materials.
It is convenient to design ER Diagrams using ConceptDraw DIAGRAM software. ConceptDraw DIAGRAM extended with the Entity-Relationship Diagram (ERD) solution supports Chen's and Crow’s Foot notations that are often used to describe database structure.

Example of DFD for Online Store (Data Flow Diagram)

Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

Financial Trade UML Use Case Diagram Example

This sample represents the actors, use cases and dependencies between them, and also the relationships between use cases. There are used dependency and use case generalization associations on this UML diagram. Use case generalization is used when you have two similar use cases, but one of them does more than another.
This sample shows the work of the Financial Trade sphere and can be used by trading companies, commercial organizations, traders, different exchanges.

Multi Layer Venn Diagram. Venn Diagram Example

To visualize the relationships between subsets of the universal set you can use Venn diagrams. To construct one, you should divide the plane into a number of cells using n figures. Each figure in the chart represents a single set of, and n is the number of represented sets. Splitting is done in a way that there is one and only one cell for any set of these figures, the points of which belong to all the figures from the set and do not belong to others. The plane on which the figures are represented, is the universal set U. Thus, the point which does not belong to any of the figures, belongs only to U.
