I didn't create a user when using the Oracle database. When using the software to connect to the database, the user name uses System so later, all the standards that belong to the SYSTEM user is in the quaternary space. Now I have created a user, put all the data above the SYSTEM to the new user, but I found that the table space of all the data I imported in the table is derived from the table. In space. I don't know who can help me solve, thank you!
