[net.micro.pc] Lan database systems

    A very major new application for PCs has arrived relatively un-noticed
with the recent advent of the multi-user lan oriented database system and,
apparently with it, one of the few remaining reasons for having multi-user
computers on the planet may be disappearing.  The rationale is as follows:
given a lan with one AT class machine with a voice-coil disk (or a 3-server
or some such animal) whose only task in life is loading and unloading data
records, along with a system in which the actual computational load involved
in a dbase system was parceled out amongst 30 PCs, it seems more than likely
that such a system would outperform a system in which an ordinary dbase was
being used by 30 people on a super-mini or mainframe computer, and for a 
fraction of the cost.

    Clearly, the PC software of the past (DBASE III etc.) won't suffice for sucha use.  Users of such a system would demand the multi-level securities, record-
locking features etc. that they were accustomed to on mainframe dbase environ-
ments.  Several vendors are now attempting to market products with these
characteristics.  Aside from network versions of DBASE III and RBASE, there is
the Lan-Datastore product which Xerox uses, and the Informa and Team-Up 
packages sold by Unlimited Processing of Jacksonville, Fla.

    I would appreciate hearing from anyone with any experience with these new
products, especially anyone having done any actual performance comparisons
between such a lan system and an equivalent system on a larger computer, as
well as anyone who has done any comparisons of the lan based products.  
Replies may as well be posted to net.micro.pc, since others may be interested.
