Description: Entity integrity is a fundamental property in database design that ensures each entity within a database is unique. This is achieved through the implementation of primary keys, which are attributes or combinations of attributes that uniquely identify each record in a table. Entity integrity is crucial to avoid duplicates and ensure data accuracy, which in turn helps maintain the consistency and reliability of the stored information. Without this property, database systems could face significant issues, such as confusion between similar records or the inability to properly track relationships between different entities. In summary, entity integrity is not just a theoretical principle but also an essential practice in data management that directly impacts the quality and usefulness of information in various technological applications.
