What is the difference between data validity and data integrity?

Difference number one: Data validity is about the correctness and reasonableness of data, while data integrity is about the completeness, soundness, and wholeness of the data that also complies with the intention of the creators of the data.
Difference number two: Data validity errors are more common, and data integrity errors are less common.
Difference number three: Errors in data validity are caused by human beings - usually data entry personnel - who enter, for example, 13/25/2010, by mistake, while errors in data integrity are caused by bugs in computer programs that, for example, cause the overwriting of some of the data in the database, when somebody attempts to retrieve a blank value from the database.
