Abstract: In one embodiment, a computer-aided dispatch (CAD) system includes a database for storing data originated at a plurality of CAD stations; a manager that manages access to the data stored in the database; and the plurality of CAD stations communicatively connected to the manager and to each other. While the manager is available, each CAD station transmits the critical data and the non-critical data originated at the CAD station to the manager and receives the critical data and the non-critical data originated at one or more other CAD stations from the manager. While the manager is unavailable, each CAD station transmits the critical data originated at the CAD station directly to all other CAD stations and receives the critical data originated at the one or more other CAD stations directly from the one or more other CAD stations.

Abstract: In one embodiment, a computer-aided dispatch (CAD) system includes a database for storing data originated at a plurality of CAD stations; a first manager that manages access to the data stored in the database; one or more second managers communicatively connected with the first manager; and the CAD stations. Each one of the second managers is communicatively connected with particular ones of the CAD stations. The particular ones of the CAD stations communicatively connected with the same second manager are communicatively connected with each other. For each one of the second managers communicatively connected with the particular ones of the CAD stations: while the second manager is available, the particular ones of the CAD stations exchange data via the second manager; and while the second manager is unavailable, the particular ones of the CAD stations exchange data directly with each other.
