A range control restricts the permissible values for data by setting a minimum and/or maximum value. This helps ensure data integrity by preventing incorrect or invalid data from being entered. Input masks, default values, primary keys, and candidate keys are all methods for ensuring data integrity, but they do not necessarily restrict the permissible values for data.
