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.
