This illustration shows the inst1.net database with two tablespaces: sales_tbs1 and sales_tbs2. This tablespace set is cloned at different times. Each time the tablespace set is cloned, a new version of the tablespace set is added to the tablespace repository. The illustration shows two versions in the tablespace repository: v_q1fy2005 and v_q2fy2005. 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. The q1fy2005 directory object stores the files for version v_q1fy2005, and the q2fy2005 directory object stores the files for version v_q2fy2005.
