For example, imagine three databases (A, B, and C) that want to replicate change request information between each other, and possibly hand over control. Using the Point-to-Point topology, database A can generate to B and C any change requests that it wants to either send, or hand over control. Similarly, database B could generate change requests to A and C, and database C could generate change requests to A and B. When only two or three databases are involved, this methodology is the simplest DCM replication topology.
