morocco-iceberg Posted July 15, 2010 Share Posted July 15, 2010 Sorry if this is in the wrong section, it was the most relevant I could find. I have an assignment where I am required to create both a Relational Schema and ER Diagram, but I always thought an ER Diagram was a form of Relational Schema, and I wasn't taught about Relational Schema in class, only ER Diagrams. Basically my question is are they different, and if so how would I draw a Relational Schema? Quote Link to comment Share on other sites More sharing options...
fenway Posted July 15, 2010 Share Posted July 15, 2010 The schema is the actual database -- the ERD is just a diagram indicating abstract concepts. Quote Link to comment Share on other sites More sharing options...
