ProductID
OrderID + ProductID
Answer:
b
Explanation:
OrderID + ProductID is an example of a composite key in a database table. The correct option is 4.
What is composite key?A composite key is a key in a database table that consists of two or more columns that uniquely identify each row.
In a database table, a composite key is the combination of OrderID and ProductID in a table that tracks sales transactions.
Because a single order can contain multiple products and multiple orders can contain the same product, neither column can uniquely identify a row by itself.
However, by combining the two columns, each row can be uniquely identified, ensuring that the data is accurate and complete.
Similarly, a combination of CustomerID and ProductID might be used in a sales system to track the products purchased by each customer.
Thus, the correct option is 4.
