Some background, this database stores data in a hierarchy data structure using a B+tree. I did some writing about this a while back, and talked to some of the developers. What's interesting about this database is that for specific use cases, it'll blow a plain old RDMBs out of the water in terms of performance because they've written a query optimizer and an execution engine that can take advantage of the proximity of related records.
At long last!
