In [[computer science]], '''data validation''' is the process of ensuring [[data]] have undergone [[data cleansing]] to ensure they have [[data quality]], that is, that they are both correct and useful. It uses routines, often called "validation rules" "validation constraints" or "check routines", that check for correctness, meaningfulness, and security of data that are input to the system. The rules may be implemented through the automated facilities of a [[data dictionary]],<ref>{{Cite web|url=|title=Data dictionary|last=|first=|authorlink=|last2=|authorlink2=|date=|website=|publisher=video 18+|others=|archive-url=|archive-date=|access-date=}}</ref> or by the inclusion of explicit [[application program]] validation logic of the computer and its application.
