Although any one replication involves only two databases, it's possible to set up chains of replications between any number of databases. This creates a directed graph, with databases as nodes and replications as arcs. Many topologies are possible, from a "star" with one master database and a number of replicas, to a mesh network where changes made at any node eventually propagate to all the others.
