Replication Technologies
Introduction
One of the key benefits of a data replication system is that data is made available locally, rather than through potentially expensive, less reliable, and slow connections to a single central database. Data is accessible locally even in the absence of any connection to a central server, so you are not cut off from data in the event of a failure of a long-distance network connection.
Replication improves response times for data requests for two reasons. Retrieval rates are faster because requests are processed on a local server, without accessing a wide area network. Also, local processing offloads work from a central database server so that competition for processor time is decreased.
