Data integrity refers to the accuracy and consistency of data over its lifecycle. It ensures that data remains unaltered and reliable, whether it is being stored, processed, or transmitted. Maintaining data integrity is crucial for making informed decisions and ensuring that information is trustworthy. There are various methods to uphold data integrity, including validation checks, error detection, and access controls. Organizations often implement these measures to protect data from corruption, unauthorized access, or loss. By prioritizing data integrity, businesses can enhance their operational efficiency and maintain compliance with regulations related to data management, such as those outlined by GDPR or HIPAA.
