The errors encountered during validating the data input.

The errors encountered during validating the data input. The data validation is the process of performing checks on data input to ensure that a program operates on clean, correct and useful data. 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 validation rules may be implemented through the automated facilities of a data dictionary, or by the inclusion of explicit application program validation logic, or by the some validation framework.
