Give an example of a validation rule used when creating an offender record.

• A. Mandatory fields: offender ID, name, date of birth; date formats; unique ID; cross-check to ensure not duplicate
• B. Allow empty fields
• C. Ignore date formats
• D. Permit duplicates

Answer: (A)

Validation rules for creating an offender record ensure data quality and consistency. They enforce that essential information is present, dates follow a standard format, and the system prevents duplicates, so records are reliable and searchable.

The best example includes requiring key fields like offender ID, name, and date of birth; enforcing a specific date format; ensuring the ID is unique; and performing a cross-check to detect duplicates. This combination protects data integrity by guaranteeing that every new record has the necessary information, uses consistent date representations, and cannot create more than one record for the same offender.

If fields were allowed to be empty, dates could be entered in various formats, or duplicates could be created, data quality would suffer and searches would be unreliable.
