Questions & Step-by-Step Solutions
In an ER diagram, what does a diamond shape represent?
Step 1: Understand what an ER diagram is. It is a visual representation of entities and their relationships in a database.
Step 2: Identify the shapes used in an ER diagram. Entities are usually represented by rectangles, and relationships are represented by diamonds.
Step 3: Focus on the diamond shape. When you see a diamond in an ER diagram, it indicates a relationship.
Step 4: Recognize that this relationship connects two or more entities. For example, a diamond might connect 'Student' and 'Course' to show that students enroll in courses.
