Discussion
One common design problem when designing a database from existing data is the presence of missing values, called blank values, in received data.
Answer: B
Correct answer: False
The statement is right about the problem and wrong about its name. Missing values are called null values, not blank values, and the distinction matters because a null is not an empty string - it is the absence of a value, and it may mean unknown, not applicable, or simply not yet entered.
