db time, cpu time, and wait time

Does anyone have a script written for the OEM repository showing for the
previous day, the cpu time and wait time for each database>?  I am looking
for something like:

                September 2, 2010

Database      CPU Time (min) Wait Time (min)
============= ============== ===============
DB1           2,134           123,123
DB2           10,231          23,234

Can anyone show me which mgmt$ views to use?
