Validity - definitions

Validity - A characteristic of Information Quality_ measuring the degree to which the data conforms to defined business rules. Validity is not synonymous with accuracy, which means the values are the correct values. A value may be a valid value, but still be incorrect. For example, a customer date of first service can be a valid date (within the correct range) and yet not be an accurate date.
