Is there a ORM Library for c++?

[Colin Song]

Is there a ORM(O/R Mapping) library for c++? Like toplink, hibernate
in java.
I can't find one in the internet. Is there any difficulty to implement
it in c++?
Or it's performance is poor ?

I don't know but I saw a ABC (A/B Computation) library the other day.
