Databasintegritet refers to the accuracy, consistency, and reliability of data within a database system. It is a critical aspect of database management, ensuring that the data is trustworthy and can be relied upon for decision-making and operational purposes. There are several types of database integrity, including:

Entity integrity, which ensures that each record in a table is unique and that the primary key values are not null. Referential integrity, which ensures that relationships between tables remain consistent. Domain integrity, which ensures that data values adhere to predefined rules and constraints.

Maintaining database integrity involves implementing various techniques and mechanisms, such as constraints, triggers, and validation rules. These tools help enforce the rules and regulations that govern the data, preventing errors and inconsistencies. Regular audits and backups are also essential for maintaining database integrity, as they allow for the detection and correction of any issues that may arise.

In summary, database integrity is a fundamental concept in database management, ensuring that data is accurate, consistent, and reliable. By implementing appropriate techniques and mechanisms, organizations can maintain high levels of database integrity, supporting their operations and decision-making processes.
