What is the main difference between data verification and data validation?

Data Validation and Data Verification are two important processes of making sure that data possesses these two qualities. Data validation makes sure that the data is clean, correct and meaningful, while data verification ensures that all copies of the data are as good as the original.

What is the difference between verification and validation?

Verification checks whether the software confirms a specification whereas Validation checks whether the software meets the requirements and expectations. Verification finds the bugs early in the development cycle whereas Validation finds the bugs that verification can not catch.

Which comes first verification or validation?
