Yep, it usually takes me a while, but I always get there in the end. :-)

Neural hashing? What on earth is that? Are you talking about using neural networks? And what would you let these networks do? Decide which transactions go first? What transactions should be rollbacked? Or what?

No you don't. You first have to find out *if* there is a statistical connnection. :-) Maybe you should first simply build a simulation of a database (or a real one) and see if you can find any statistical relationships.

Good question. I'm afraid I don't know any.

Yes, there is. That reminds me; I have to get back to work now. :-)
