Entity-Relationship Diagram (ERD)

How to Create an ERD Diagram

ERD (entity relationship diagram) is used to show the logical structure of databases. It represents the interrelationships between components of database (entities). Entity relationship diagrams are a widely used in software engineering. Using ERD software engineers can control the every aspect of database development. ER diagram can be used as guide for testing and communicating before the release of software product. ERD displays data as entities that are connected with connections that show the relationships between entities. There is some ERD notations used by data bases developers for representing the relationships between the data objects. ConceptDraw PRO and its ERD solution allow you to build ERD diagram of any notation.

How to Create a Venn Diagram in ConceptDraw PRO

Venn diagrams were invented by John Venn as a method of depicting relationships between different components. A Venn diagram consists of two or more circles. Each circle represents a specific group or set. The entities which are depicted by circles generally have some common characteristics. A Venn Diagram shows all the possible logical relations between these entities. Any properties that belong to more than one set should be indicated in the sections where the circles overlap. A Venn Diagram can be useful to visually summarize the status and future viability of a project. ConceptDraw PRO allows you to make a Venn diagrams using the Venn Diagrams solution.
