Static data in Lara must be inserted in the intermediate database when the PrismilClient is launched.
Once database are synchronised, the PrismilClient will subscribe to events concerning creation or change of reservations.

Google Earth extension to CDRs Availability Slony-I
is an asynchronous master-slave replication system for the PostgreSQL DBMS. Asynchronous means that when a database transaction has been committed to the master server, it is not yet guaranteed to be available in slaves. Cascading means that replicas can be created (and updated) via other replicas
