Dataintegriteetti

Dataintegriteetti, or data integrity, refers to the maintenance and assurance of the accuracy, consistency, and completeness of data over its entire lifecycle. This means that data remains unchanged from its creation to its deletion, or that any changes are authorized, tracked, and recorded. Maintaining data integrity is crucial for organizations to make reliable decisions, comply with regulations, and ensure the trustworthiness of their information systems.

There are several key aspects to data integrity. Accuracy ensures that data is correct and free from errors. Consistency means that data is uniform and doesn't contradict itself across different storage locations or over time. Completeness guarantees that all necessary data is present and available. Finally, data integrity also encompasses aspects of security and access control, ensuring that only authorized individuals can modify or delete data.

Data integrity can be compromised by various factors, including human error, hardware failures, software bugs, and malicious attacks. To safeguard data integrity, organizations implement a range of strategies. These include employing robust data validation techniques to check for errors upon entry, utilizing checksums and hash functions to detect unauthorized modifications, establishing strict access controls and user permissions, performing regular backups and recovery procedures, and implementing audit trails to track all data changes. Adherence to data integrity principles is fundamental for effective data management and the overall reliability of information systems.
