Is there a way to revoke DDL privileges from a user

Question

I would like to revoke DDL privileges from a user.
My requirement goes like this
1.Create a user with DDL privileges
2. Create the required tables in that user. Fill the data.
3. Revoke DDL privileges from that user (CREATE,ALTER,DROP).
I was able to achieve this by creating two users where in the 1st user contains all the physical objects and data, where in the 2nd user contains only synonyms with select/execute privileges.
Is there any other way to achieve this.
Bcoz in SQL SERVER 2005 we have
REVOKE ALTER TABLE FROM USER; and likewise.
Kindly help me out!
Thnx in advance

You can easily satisfy all your requirements using facilities provided by the database. Here is a sample:
SQL> create user test identified by test;
User created.
SQL> grant create session to test;
Grant succeeded.
SQL> connect test/test
SQL> CREATE TABLE ddl_in_my_schema(x number);
CREATE TABLE ddl_in_my_schema(x number)
ERROR at line 1:
ORA-01031: insufficient privileges
-- Connect as administrator
SQL> GRANT CREATE TABLE TO test;
Grant succeeded.
SQL> ALTER USER test QUOTA 10M ON USERS;
User altered.
SQL> connect test/test
Connected.
Session altered.
SQL> CREATE TABLE ddl_table(x number);
Table created.
SQL> INSERT INTO ddl_table SELECT OBJECT_ID FROM ALL_OBJECTS;
4468 rows created.
-- Connect as administrator again
SQL> REVOKE CREATE TABLE FROM test;
Revoke succeeded.
SQL> connect test/test
Connected.
SQL> CREATE TABLE ddl_table2(x number);
CREATE TABLE ddl_table2(x number)
ERROR at line 1:
ORA-01031: insufficient privileges
