>What is the difference between verification and validation?

** When I was documenting data-processing software a few years ago,
it was considered that validation answers the question "Does it
make sense?" and verification answers the question "Does it tell
the truth?"

Listing Bill Clinton's birthday as August 43, 1946, would fail
validation because there can be no such date. Listing it as
August 4, 1946, would pass validation but fail verification
because it is factually incorrect.
