Which concept ensures the accuracy and consistency of data within a database?

The concept that ensures the accuracy and consistency of data within a database is information integrity. Information integrity refers to the maintenance of, and the assurance of, the accuracy and consistency of data stored in a database. This concept is crucial because it helps prevent corruption, unauthorized access, and inconsistencies that may arise from data alterations over time or through improper procedures.

Maintaining information integrity involves various practices such as validating input data, enforcing data standards, and implementing access controls, which collectively help ensure that data remains reliable and trustworthy. When information integrity is robust, decision-making processes become more effective, as stakeholders can trust the data they are using.

In contrast, other concepts like information management deal broadly with how information is handled within an organization, including how it is collected, stored, and used. Data warehousing focuses on the storage of large volumes of data from different sources in a manner conducive to analysis, while data mining involves extracting patterns or knowledge from large sets of data. While these concepts relate to data and information systems, they do not specifically focus on the accuracy and consistency of data itself in the same way that information integrity does.
