I have just posted a tool (qqCDR) on the web - it's an interface to allow for Call Detail Reporting Queries from the Callmanager CDR Database without all the headache of ART/CAR. Something like this has been a long time coming, hopefully it can be of some use to some of you in your CDR quest!
Right now it's just good for callmanager, it doesn't work with CCME, but I'm toying with the idea of working on an interface there.
If anybody wants to check it out -

The demo is a free download.
Cheers!
