ooRef vs. ooHandle
Objectivity/DB provides two special classes that may be used to access persistent objects: object references (ooRef) and handles (ooHandle). In BaBar, you are likely to see BdbRef and BdbHandle instead of ooRef and ooHandle. ooRef and BdbHandle are simply typedefs, they directly map to ooRef and ooHandle.
The ooRef class is optimized for space. The ooHandle class is optimized for speed and contains additional information that provides more efficient access to multiple fields in the same object.
