BO 4.x Auditing vs BO 3.x Auditing

Hi,

Once we enable auditing, is it possible to know

1) all the universes accessed by the end user?

2) what are the objects that he has accessed from those universes?

3) when did he access those universes etc.,?

4) Would the ADS_Event table in 4.x Audit schema give those details?

5) Are there any equivalent tables in 3.x?

Please help.

Thanks in advance.
