Yes.

Look at FILE_NAME, AUTOEXTENSIBLE and INCREMENT_BY in DBA_DATA_FILES.

is dba_data_files specific to tablespaces, or does it list information on other things above and beyond tables spaces. or is it a tidy view 1 row per tablespace?

Tablespaces do not autoextend.  Only data files do.

A tablespace can have one to many datafiles.

A datafile belongs to one and only one tablesapce.

is there also anywhere to see a list of all default oracle tablespaces that would be evident in every database?

in which case is there anywhere to tie up datafiles and tablespaces, to see which datafiles are in which tablespace?

>>is there also anywhere to see a list of all default oracle tablespaces

The only real 'DEFAULT' tablespace is SYSTEM and I'm not 100% sure you cannot rename that one when creating a database.  There are some  sort of standard ones in the templates but they are up to the DBA that creates them.

You can see ALL tablespaces in, guess which view?  DBA_TABLESPACES.

Oracle is pretty good about naming the views.

Three levels:  USER_, ALL_ and DBA_ then the object you are looking for.

Differences:  USER is objects the USER owns.  ALL, the objects the user has permission to see, DBA everything in the database.

Looking for say, INDEXES?  DBA_INDEXES.

>>to see which datafiles are in which tablespace?

dba_data_files also has a TABLESPACE_NAME.

Depending upon the scripts used to install the database, there could be additional non-default tablespaces at creation time, but try:

select t.name, min(creation_time) creation
from v$datafile d, v$tablespace t where d.ts#=t.ts#
group by t.name
order by 2
/

Your results should resemble:

NAME                           CREATION
------------------------------ ---------
SYSTEM                         06-JUL-12
SYSAUX                         06-JUL-12
UNDOTBS1                       06-JUL-12
USERS                          06-JUL-12
RMAN                           06-JUL-12

>>v$datafile d, v$tablespace t

I suggest using the views based on the USER/ALL/DBA labels over the V$ views for static objects.  The V$ views can be confusing.

That particular question is answered, then.  Does that help or are we missing your intent?
