- We (Expert Solutions Australia) have developed a non-relational
- database that does all these things: replicated/redundant,
- synchronous, disk caching (for catastrophic) recovery, "active"
- (it can distribute updates to interested parties), etc, and it's
- fast. We are in the process of putting an SQL front-end onto it to
- make it more user-friendly. If anyone is interested, I have a
- paper on it I can mail to you (nroff -mm or PS format). It is not PD.
