A very small database may need only the SYSTEM tablespace; however, Oracle
recommends that you create at least one additional tablespace to store user data
separate from data dictionary information. This gives you more flexibility in
various
database administration operations and reduces contention among dictionary
objects
and schema objects for the same datafiles.
1. 一个数据库最少需要system表空间
2. 使用多个表空间 , 你可以将用户数据与数据字段分开
,减少同一数据文件在系统和用户对象之间的竞争[@more@]
