Some (Single System) Advantages

•Minimal abstraction between interface and data (speed, fewer points of failure)

•Minimized queries per page: O(1), not O(n)

•Maximize caching opportunities due to small data elements

•Native optimistic reads


Some (Multi System) Advantages

•Each node has its own store (reduced contention)

•Mirroring of data segmentations for write control

•Theoretical ability to combine data from multiple writes; eventual consistency (RDF as fifth normal form with sufficient provenance information; currently unimplemented)
