Q: What is the role of attributes in an ER model?
Solution: Attributes provide additional information about entities in an ER model.
Steps: 5
Step 1: Understand what an ER model is. An ER model (Entity-Relationship model) is a way to represent data and its relationships in a structured format.
Step 2: Identify what an entity is. An entity is a thing or object in the real world that can be identified, like a person, place, or item.
Step 3: Learn about attributes. Attributes are characteristics or properties that describe an entity. For example, if the entity is 'Student', attributes could be 'Name', 'Age', and 'Student ID'.
Step 4: Recognize the role of attributes. Attributes provide additional information about the entities, helping to define them more clearly.
Step 5: Understand that attributes help in organizing data. By using attributes, we can store specific details about each entity, making the data more useful.
