Replication is the act of creating (normally automatically) a duplicate copy of a database or file system on a different computer. The term usually implies the intelligent copying of parts of the source database which have changed since the last replication with the destination. |

Replication may be one-way or two-way. Two-way replication is much more complicated because of the possibility that a replicated object may have been updated differently in the two locations in which case some method is needed to reconcile the different versions. |

* [LDAP] (and implementations like ActiveDirectory) can be set up across multiple servers, so you query any one and get the same information, because they replicated between them. |
