Most vendors use three indexes for triples and 4 or 6 for quads. All the indexes are covering, which is to say they triplicate all data—-in other words the database consists only of indexes.

Aint that just neat?

I refer to RDF as the "absurd normal form". When my friends and I do DB design, it's almost inevitable we fall into what might inevitably become the "ThingThing" table thats a many-to-many joiner of everything to everything else. (That's when we giggle, leave the room, go to lunch, and then come back when we've returned to our senses.)

But, for RDF its exactly what I want, I'm not interested in schemas and such for this work, so it's perfect for my scenario.

The killer feature isn’t even fully indexed queries for ever, it’s the serialization formats.

Need to do a non-trivial merge of complex domain graphs? Why have you tried string concatenating turtle files?
