A replication is some aspect of the distributed database system that is replicated from the user (programmer, system developer and user or application program). A replication is provided by including some set of mechanisms in the distributed system at a layer interface where the replication is required. A number of basic replications have been defined for a distributed system. It is important to realize that not all of these are appropriate for every system or are available at the same level of interface.
