Validation rules are crucial for ensuring the accuracy and integrity of data within a system. They help prevent errors by enforcing specific criteria that data must meet before being accepted, thereby minimizing the risk of flawed information entering the database. This not only enhances data quality but also improves decision-making processes and operational efficiency. Additionally, validation rules can help maintain compliance with regulatory standards and business policies.
