guide:
  ~Transportable tablespaces are also useful to move data from the data
   warehouse to a dependent data mart.
  ~In oracle 10g, it is feasable to transport tbs between operating systems.
   like Windows to Linux.

step by step:
  1. Create a new tablespace
  2. Move the data you want to transfer into its own tablespace.
  3. Alter the tablespace to read-only.
  4. Use the export utility to unload the metadata describing the objects in the
     tablespace.
  5. If moving between different operating system, then convert the files using
     RMAN(this conversion step can alternatively be permormed on the target platform
     after step 6)
  6. Copy the datafiles and export dump file containing the metadata to target
     system.
  7. Use the import utility to load the metadata descriptions into the target database.
  8. Alter the tablespace to read/write.
  9. Perform transformations
 10. Move the data from the staging area to warehouse fact table.

   Each tablespace must be self-contained and cannot reference anything outside
 the tablespace. If there were a global index on the Apirl ORDERS table, it would
 be not self-contained, and the index would have to be dropped before the tablespace
 could be moved.

    When we create the archiveture, we should think about issue about characterset first. 
  Any characterset conversion is danger for underlying data. Before you begin the conversion
  the any data would be backuped.
