RHIC Data Object Description

Data Description

CDEV Object Names

The rhic monitored data is stored in the rhic CDev database in objects called devices.
Each device contains a set of data parameters.  The following table contains the CDEV
device types and the names by which they are accessed by client applications. Each name identifies a unique
device type object which is stored in the CDEV database.
