The db4o to db4o replication allows you the keep multiple, independent db4o -databases in sync. A typical scenario is when a mobile device is synchronized periodically with the central server or a desktop application
dRS supports simple unidirectional replication where changes are replicated in one direction. See "Simple Example"
In addition dRS support bidirectional replication, where changes are replicated in both directions. See "Bidirectional Replication"
To avoid replicating the whole database, dRS support also partial replication, where only a subset of all objects are replicated. See "Selective Replication"
Furthermore dRS can also replicate deletions of objects. See "Replicate Deletions"
