Re: Alternatives to ACID, non-serialized concurrent transactions?

todd,

yes, there are theortical models, and probably some implementations. to address the considerations you are asking about. you should do a review of literature on neural networks and their supporting databases.

it is important to remember that parallel processing requires parallel CPUs and parallel architectures. comparing general purpose applications (sequentail processing) to those that require real time, parallel processing, there are very few of the latter. there are also few real time applications that require "large" databases. the best example i can think of at the moment of a near real time application with a large database is the new york stock exchange. NYSE buys a lot of cache memory.

keep in mind ACID is for transactional databases. there are many other kinds of databases where ACID is not significant. Received on Tue May 06 2003 - 18:41:57 CEST
