consistency checking

Consistency checking is the process of verifying that information or data aligns logically and doesn't contain contradictions. In systems like databases, it ensures that all data follows predefined rules and matches expected relationships, maintaining accurate and reliable information. For example, it would detect if a record shows a person's birth date as after their death date. By identifying inconsistencies, it helps maintain data quality, supports correct decision-making, and prevents errors caused by conflicting information.
