can we find unused tables and markings using OEM 12 c

Hello

I use OEM 12 c, databases are all about 11.2.0.3 and need to find if I can find many empty tables and markings unused acorss our env using OEM 12 c
DBA create tables and indexes intended to test dummy and then they forget to delete these objects that are not been used for a long time.
can I use a time regarding since when they are not being used and if they are empty using OEM 12 c.

Thank you

Don't know if EM can be used for this but you can use the audit to see if tables/indexes are used. See http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_4007.htm#i2116021

Just to know if indexes are used, you can use ALTER INDEX USE of SURVEILLANCE;
For more information, see http://www.oracle-base.com/articles/10g/index-monitoring.php
