Entity Relationship Diagram (ERD) for Website

By: Stanley Yun Kai Fok

(freepik, 2017)

Using Drawio, I created an Entity Relationship Diagram for my website database. Its entities, attributes, relationships, and cardinalities are identified in the illustration.

Legend:

Rounded Rectangle = Entity

Oval = Attribute

Diamond = Relationship

Cardinality Ratios - one-to-one; one-to-many
