Methods to improving the reliability of storage of information in databases

Abstract

In the article written about the ways of improving the reliability of data storage in databases, and given the
concepts of RAID arrays, correction codes and the term “Big Data”. Also there is shown the relevance of the problem
of reliability of storage media that has arisen recently, because of sharp increase in the volume of stored information.
There is suggested ways of using codes with erasures which can increase data storage reliability with much less
redundancy than using replication which help to reduces overhead.
