Sometimes Application team might asked you to provide details of last modified table in oracle. So just run the below query :
set linesize 500;
select TABLE_OWNER, TABLE_NAME, INSERTS, UPDATES, DELETES,
to_char(TIMESTAMP,'YYYY-MON-DD HH24:MI:SS')
from all_tab_modifications
where table_owner<>'SYS' and
EXTRACT(YEAR FROM TO_DATE(TIMESTAMP, 'DD-MON-RR')) > 2010
order by 6;
