Yes, came here to say that as well. I hear people saying 'Oracle can scale as well'; that could be true, or not. I don't know: I don't have a lot of experience with Oracle on large scale projects (I did a lot of J2EE projects using Oracle, but those really could've just as well worked on SQLite, and I mean that... Complete overkill.). I know my database theory and I don't understand how Oracle can scale like a NoSQL database while preserving their RDBMS nature; as I understand that's not possible right?

So how is there no room for NoSQL databases? I understand that most sites running NoSQL at the moment could just as well (or even better) run on Postgresql, even with 'biggish data', but is for 'enormous' data and near real time analysis of it, NoSQL not a proper solution over 'traditional' RDBMSs. Not trolling; really curious what people have to say.

Do I understand it correctly that Oracle 'Exadata' just uses fiber cables and such to threat the entire rack as 'one node' or does it work differently? How does Oracle scale? Any information about that (tech information, not opinions/interpretations of reality as OP posted)?
