In Oracle database dba_data_files is the dame as v$datafile and dba_temp_files is the same as v$tempfile. What is the equivalent for dba_free_space?

Also what is the difference between using dba_data_files or dba_temp_files instead of v$datafiel and v$tempfile in a query? Is there any? Or is it exactly the same?

One thing I know id both v$datafile and v$tempfile are accessible from standby database and dba_date-files or dba_temp_files are not. Anything else?

Howdy, Stranger!
