Performance view V$SEGSTAT and V$SEGMENT_STATISTICS.
This view has a lot more columns and is more descriptive with respect
to the object identification. In addition to columns like the main
view, it also references the names of the tablespace, the object, and
the owner etc. so that the user can quickly join the view with actual
names.
