Field validation ensures that a program or form is using clean incorrect data. A set of validation rules are used to check data that is entered into a system before it is processed.

Validation rules help maintain the integrity of a database by enforcing data accuracy and consistency. They ensure that only valid data entries are allowed, preventing errors such as incorrect data types, values out of range, or missing values. This helps in maintaining data quality and reliability within the database.
