The ER diagram includes 6 entities: user, category, article, label, publisher, and source. Each entity has its own attributes, and there is a certain connection between the entity and the entity. As the name suggests, an ER diagram depicts the relationship between two or more entities. This could be real-world entities or entity sets of a database. The model helps us build a logical structure of the database or the overall connectivity in software development. Check more details from this er diagram, or make yours with ease!
