database integrity

Database integrity refers to the accuracy, consistency, and reliability of data stored in a database. It ensures that the information remains correct and trustworthy over time, preventing errors, duplicates, or data corruption. This is maintained through rules and controls, such as validating data entries, enforcing relationships between data, and restricting unauthorized changes. Essentially, database integrity makes sure that the data consistently reflects the real-world information it represents, allowing users to depend on its quality for decision-making and operations.
