I've not looked at the SQL standard, but it seems to me like the order
should be:

Databases
   Tablespaces
      Schemas
         Objects (tables, indexes, functions, etc.)

And it really isn't hierarchical.  As I understand them (based on my
Oracle background), tablespaces, unlike schemas, do NOT create a layer
of data abstraction.   That is to say, while the same table name
can exist in multiple schemas, only one instance of a given table name
within a given schema can exist, regardless of what tablespace it is in.

That makes the tablespace a property of an object.

Whether or not two databases can share tablespaces isn't clear to me,
though as a DBA I can think of good reasons why they probably shouldn't
do so, I'm not sure if that is an absolute.

I'm game, though I'm also not ready to lead such a project, probably not
even the discussion on it.
