No, I don't think so. Explaining "Consistency" they write:

"There is no system mechanism that prevents a user from entering a bad transaction, e.g., crediting the wrong amount to a bank account, or charging for an item that was not shipped."

This is clearly referring to correctness, no?

I was under the impression that the terminolgy and interpretation of ACID was pretty much agreed on, but this paper call the 'C' Consistency but appear to mean "Correctness." Received on Mon Aug 21 2006 - 12:12:41 CDT
