Hi,
I just see that Mysql will propose at the end of the month a full
synchronous replication system with auto-recovery. http://www.mysql.com/products/cluster/
We need to see when stable version would be released.....
I use PostgreSQL and I would appreciate to have the same features in
PostgreSQL.
Any comments ? (no flame, please)
Cordialement,
Jean-Gérard Pailloncy

Quoth uw*@oss4u.com ("Uwe C. Schroeder"): I concur. However the problem SAP had some 18years ago when they
invented their system were massive differences between
databases. The scope they had in mind didn't allow for whole
database layers to be redundant just for the sake of being able to
talk to several database engines - ergo they wrote one layer and
omitted using vendor dependant database features. Nowadays most
relevant databases are pretty compatible when it comes to
constraints, so if you stick to the basics you should be fine now.
One of the issues was always that of locking. Different systems still
have different semantics.

I've implemented a parser combinator library in Generic C#, and indeed
what is pretty clear in a functional language looks extremely
scientific in an object-oriented one. -- Peter Sestoft

That's spelled "down". Access is almost 100% SQL-92 compliant, allows
subselects, and does pretty good query optimization. MySQL has nothing
on it. And, no, I'm not some Microsofty.

Hi,
I've been using an Access application I wrote for an office with the
front-end stored on all computers and the back-end on one of them serving as
an Access file server.
Now we're moving to a 2nd office 15 minutes down the road. Only one office
will be open at a time, so theoretically it'd be possible to copy the
back-end manually every night from one office to another, but frankly,
that's pretty annoying.
