Hi Vili,
The Oracle dba_tables view keeps the date_created for all tables, but it goes away after the table has been deleted.
Check the last_ddl_time in dba_objects.
You may need the dictionary reference poster:

>> i want to know the tables that was created or the tables that have modificacions from 01/02/2011 to 01/09/2011 by 'SYSTEM' user
The SYSTEM user should never create objects!
Try something like this:
CODE
select,
object_name,
object_type,
last_ddl_date
from
dba_objects
where
last_ddl_date > sysdate - 7;
