Q: In an ER model, what does a diamond shape represent?
Solution: In an ER model, a diamond shape represents a relationship between entities.
Steps: 4
Step 1: Understand what an ER model is. It is a way to represent data and how different pieces of data relate to each other.
Step 2: Identify the shapes used in an ER model. 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 model, 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.
