    - The following are a few data dictionary and dynamic performance views provide useful information about the tablespaces of a database.

    - V$TABLESPACE - Name and number of all tablespaces from the control file.

    - DBA_TABLESPACE_GROUPS - Displays the tablespace groups and the tablespaces that belong to them.

    - V$DATAFILE - Information about all datafiles, including tablespace number of owning tablespace.

    - DBA_EXTENTS, USER_EXTENTS - Information about data extents within all (or user accessible) tablespaces.
