A process for distributing data from a source database to target databases while usually keeping the databases synchronized.

The process of copying a portion of a database from one environment to other and keeping the subsequent copies of the data synchronized with the original source. Changes made to the original source are propagated to the copies of the data in other environments. DAMA web site at www.dmreview.com

The process of copying data to remote locations, and then keeping the replicated data synchronized with the primary data. Data replication is distinct from data distribution. Replicated data is stored copies of data at one or more remote sites throughout a system, and it is not necessarily distributed data. Contrast with data distribution. See also disk replication and transaction replication.

Duplicates data on one or more database servers. Entire tables can be duplicated on different servers, or subsets of rows in a table can be duplicated to different servers.

Duplication of data to another system via a LAN or SAN infrastructure.
