Replication transparency

Replication transparency is a property of large-scale distributed database management systems (DBMS). When data is replicated between database servers, so that the information remains consistent throughout the database system, and users cannot tell or even know which server in the DBMS they are using, the system is said to exhibit replication transparency.

Replication helps performance by ensuring that no one server in the DBMS is used too heavily. It is also a safety measure: if one of the machines fails, a copy of the data is still available on another machine on the network.
