The Tungsten Replicator implements open source database-neutral master/slave replication. Master/slave replication is a highly flexible technology that can solve a wide variety of problems including the following:

Availability - Failing over to a slave database if your master database dies
Performance Scaling - Spreading reads across many copies of data
Cross-Site Clustering - Maintaining active database replicas across WANs 
Change Data Capture - Extracting changes to load data warehouses or update other systems
Zero Downtime Upgrade - Performing upgrades on a slave server which then becomes the master
The Tungsten Replicator architecture is flexible and designed to support addition of new databases easily. It includes pluggable extractor and applier modules to help transfer data from master to slave.
