The NOCC (National Outcomes Casemix Collection) Data Cube contains aggregated data extracted from the NOCC Data Warehouse, which, in turn, contains the results of mental health measures collected by all of the public mental health organisations in all Australian States and Territories. The earliest results in the NOCC Data Warehouse were collected in July 2000. In order to preserve the privacy of individual clients, information in the Data Warehouse is not made publicly available. However, aggregate data extracted from the Data Warehouse is deposited into the NOCC Data Cube, which ‘‘is’’ made available via a number of interfaces as described in the Technical Manual.
