Point-to-Point topology

With the Point-to-Point topology, each database generates a transfer package for either a database to which information is to be sent or a database to which control of a change request is to be handed over.

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.
