I have read and listened to many articles and even dabbled in (not necessarily successfully...yet) in the new world of NoSQL (or more accurately Map reduce) type databases. These new structures are making us reassess the way we define data. The rules of ACID (Atomicity, Consistency, Isolation, Durability) no longer apply, at least not in the way we have learned or have been taught. The new rules can be described as CAP (Consistency, Availability, Partition-tolerance). Below is a link to a very thoughtful article, not one a busy person could read through quickly and fully understand but as the article probably took weeks to write maybe it should take a few days to read. http://radar.oreilly.com/2012/02/nosql-non-relational-database.html Jim
