You build your model in the Connect CDC Director and then commit it, meaning that the model is sent to the servers where it is loaded in XML. You start requests in Connect CDC MonCon or Connece CDC Console. Each host has a Connect CDC Listener. Changes to data are captured and then pushed into replication queues. The figure below shows the Connect CDC copy architecture.
