Which of the following is an example of an attribute in an ER model?
Correct Answer: OrderID
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 attribute is. An attribute is a property or characteristic of an entity in the ER model.
Step 3: Look for examples of attributes. For instance, if we have an entity called 'Order', it can have attributes like 'OrderID', 'OrderDate', and 'CustomerID'.
Step 4: Recognize that 'OrderID' is a specific example of an attribute because it describes a characteristic of the 'Order' entity.
