===Replication===
{{See also|Replication (computing)#Database replication}}

Occasionally a database employs storage redundancy by [[database object]]s replication (with one or more copies) to increase data availability (both to improve performance of simultaneous multiple end-user accesses to the same database object, and to provide resiliency in a case of partial failure of a distributed database). Updates of a replicated object need to be synchronized across the object copies. In many cases, the entire database is replicated.
