Digital Continuity Guarantee Based on Data Consistency in Cloud Storage

摘要

Since the British National Archives put forward the concept of the digital continuity in 2007, Some developed countries have developed a digital continuity plan of action. At the same time, digital continuity has become a hot topic in electronic document research. However, there is still a lack of technologies and measures to protect digital continuity. Data usability is the foundation of digital continuity, and its focus is on making digital information readable and operational. Data consistency is the essential requirement of data usability. If there is no data consistency, then there is no data availability. Therefore, ensuring digital consistency of electronic records is the basis for digital continuity. This paper proposes a framework for verifying the consistency of electronic record data based on functional dependency theory. Moreover, an example of verifying the data consistency based on functional dependency theory is given to check the data consistency of electronic record periodically.
