I'm taking academic database classes and last semester we covered academic ERDs. The material in the book discussed 'entity sets' and relationship sets. The relations between them seemed very similiar to relations in a class diagram.
However, I when I look into Erwin and Designer the ERDs there seem to be closer to table models. Does anyone use the academic type of ERDs professionally?
