This illustration shows a CDB with a CDB$ROOT container, a PDB$SEED container plugged into the root, and several PDBs plugged into the root. One PDB is a new PDB. The illustration shows two
            options for creating the new PDB:
         
A CREATE PLUGGABLE DATABASE ... USING statement uses the unplugged PDB’s XML metadata file along with the unplugged PDB’s database files to create the new PDB.
               
A CREATE PLUGGABLE DATABASE ... USING statement uses a .PDB archive file to create the new PDB. The .PDB archive file contains the unplugged PDB’s database files
                  and the unplugged PDB’s XML metadata file that are used to create the new PDB.
