Rules can be collected through the requirements capture exercise. Therefore, data validation should start with business process definition and set of business rules within this process. Data that does not conform to these rules will negatively affect business process execution. The rules may be implemented through the automated facilities of a data dictionary, or by the inclusion of explicit application program validation logic.įor business applications, data validation can be defined through declarative data integrity rules, or procedure-based business rules. It uses routines, often called "validation rules" or "check routines", that check for correctness, meaningfulness, and security of data that are input to the system. In computer science, data validation is the process of ensuring that a program operates on clean, correct and useful data. Freebase (0.00 / 0 votes) Rate this definition:
