Ahem, your contemporary relational list procedure are able to do everything some sort of file system can. In fact, they're just the two databases, nonetheless optimized to get different projects and a little bit diverse semantics. The identical warning signs is often accomplished along with both; it is just a make any difference of pattern bias, not really capability. File methods just like ZFS essentially converge on natural MVCC databases behavior, which will durably magazines many is currently writing but together with more overall flexibility by using esteem to be able to atomicity along with edition housecleaning over a document system. File program semantics, perhaps versioning ones, tend to be more old fashioned and fewer competent in comparison with repository ones, but having considerably amplified functionality over just what exactly would be possible from an MVCC data source to the same task.
Same theory, different optimizations. The balancing work has been somewhere between the energy thoroughly ACID-compliant MVCC semantics and also the simple speed with basic file method semantics. Apple and Sun will be burning several excess performance ability to deliver features that are finer for the database ideal.
