This illustration shows that the database and the database share a computer file system. The database contains two tablespaces: sales_tbs1 and sales_tbs2. The illustration shows a tablespace repository with three versions of this tablespace set: v_q1fy2005, v_q2fy2005, and v_q1fy2005_r. Other versions can also be added to the tablespace repository. The illustration also shows the directory objects that store the datafiles, export dump file, and export log file in each version:

When a version of the tablespace set is detached from the database, the new version v_q1fy2005_r is added to the tablespace repository in Datafiles and the export dump file in the detached version remain in the q1fy2005_r directory object.
