In computer science,<unk>  is the process of ensuring<unk>  has undergone<unk>  cleansing to ensure they have<unk>  quality, that is, that they are both correct and useful. It uses routines, often called<unk>  rules",<unk>  constraints", or "check routines", that check for correctness, meaningfulness, and security of<unk>  that are input to the system. The rules may be implemented through the automated facilities of a<unk>  dictionary, or by the inclusion of explicit application program<unk>  logic of the computer and its application. This is distinct from formal verification, which attempts to prove or disprove the correctness of algorithms for implementing a specification or property.
