In database management, handling missing or unknown values is crucial for data integrity. LibreOffice Base, a component of the LibreOffice suite, provides the ability to add Null values to database tables, which represent the absence of a meaningful value for a particular field.
Null values are distinct from empty strings or zeros, as they explicitly indicate that no data is available. This differentiation is essential to avoid confusion and ensure data accuracy. Adding Null values allows database designers to model real-world scenarios where data may be incomplete or temporarily unavailable.
