Here's some relevant documentation for Schevo:

I think Schevo was initially designed as a object relational database 
management system (ORDBMS)
on top of Durus. However, since Schevo is not tightly integrated to 
Durus, it is possible to use the ZODB backend to make transactions and 
process a BTree.
