I'm working with the auditing service in Alfresco 3.4.7 EE.
Unfortunately, as far as I know, starting from the 3.4 the audit database couldn't be a accessed directly and some useful tables like alf_audit_fact are not available anymore.
I'm wondering if someone has already developed something to export the auditing information to a "universe" accessible by a standard business intelligence product (like Business Object).
the Audit component was refactored in 3.4 and audit information is now stored in the alf_prop_* tables as far as I know. Accessing the Alfresco DB schema directly is considered bad practice exactly for this reason - the abstraction layer of Alfresco services has remained stable throughout this change.
I am not aware of an export module in the community - depending on the audit application I'd expect that a generic export utility would not be that useful, as audited data might need specific processing if exported to an outside universe.
I wouldn't do that, as this is rather complex and can affect performance significantly if done improperly . It would be best to implement a query action which transfers essential data to your external database in such a scenario.
