maintenance of, and the assurance of the accuracy and consistency of, data over its entire life-cycle
Data integrity is a term used in computer science and telecommunications that can mean:
- Making sure that data is "whole" or complete.
- The conditions by which data are maintained during any operation (such as transfer, storage or retrieval).
- The correct storage of data for further use.
- The rules for measuring data quality.
Simply, data integrity is to make sure that data is "consistent" and "correct".
