- Which is better, access verification rules or validity rules?
- Access validation rules and validation rules are both tools for ensuring data accuracy, but they serve different functions. Validation rules provide complex and flexible validation that can be performed on save or update, while validation rules provide on-the-fly visual cues that are applied dynamically as you type. The best choice depends on the requirements: use validation rules for complex validation, and validation rules for visual cues and error prevention. Recommended to use in combination for best accuracy and data integrity.
