we say that data is useless, only the combination of applications and human
reasoning can turn it into __information__. so, with that in mind, i'd say
that data and applications are useless and that it's only by combining the two
using logic (aka business rules) that anything meaningful arises.

cast in point : we've 260tb of 'data' sitting in our mass storage device.
less than 0.01% ever comes back out. that small percentage is massaged into
meaningful __information__ via complex application and human logic though and
it's those kernels we're interested in.

Having trained as a physicist before entering IT I'd say that's a different usage of the word 'data' than in this conversation. I'd worry about any data entering one of my relational databases that didn't pass the basic criterion of being potentially useful information - of course it's not provably useful until someone performs a query to extract it, so perhaps we should class it as virtual information in its stored form... some kind of superposition waiting for human intervention ;p

Anyway, if I have the choice between saving my data and saving my code - data will win every time.
