"Depends." You have to test ... Depending on what API's you use
"yes," or you may happen to use one of the changed or deprecated API's
in which case the answer is "no." If you're using Project Wonder,
until the official 5.4 release is out, the answer is probably "no."
Anjo just committed some changes to the build system to make this
possible, so we should have a 5.4 build coming up soon.

Can 5.3 apps be run on Leopard server / 5.4 deployment ?
Thanks, Simon

I am sure that you can make it go, but other than clustering, why
bother? If you don't need that it seems like a lot of configuration
work, research, etc. for what FrontBase gives you with a single
click installer.

I agree with this. You also need a minimum 3 servers to have a true
cluster so it becomes incredibly expensive because you need mountains
of RAM in each server.
But if you are just looking for data security/back-up etc rather than
load balancing and true redundancy then MySQL replication is
trivially simple. We use it to keep a virtually live replica of our
production databases on a local server. You can actually do some form
of load balancing with replication by distributing SELECT statements
between slaves, but limiting UPDATE statements to the master.

Finally, I have zero criticsm for FrontBase or PostqreSQL ....
just have never had a need to go there yet .... although, I am
planning to give serious playtime to both someday soon when I get
time .... especially after all the positive comments about
Frontbase and PostgreSQL here in the community.
I've mentioned it before, but my #1 gripe about PG is that there is
no viable (non-commercial) clustering solution for it. It makes it
very hard to create a fault-tolerant deployment of it, unlike MySQL
and FB. Other than that, I really like PG.
+1000, and replication options are total crap (Slony is the less
worse, and you have to rebuild the replication when you made a change
to the schema).

I suspect they very likely have compelling performance numbers, but I
haven't had time to actually run tests with our real databases on
it ... There are graphical MySQL front-ends (whereas FB's is fine, but
sort of "passable"), and honestly there are pkg installs of it also at
this point, so it's not a WHOLE lot more than double-click-to-install
at this point. Slightly more obnoxious with permissions and users,
etc, I suspect. I think FB wins pretty handily in the competition
from zero-to-running-database, but how often are you doing that part?
In terms of % of time spent, that's only a fraction of your db's
life. I just don't want to discount it because a decade ago it
sucked.

OpenBase is another obvious choice. One that seems to be somewhat
ignored on this list, for no obvious reason.
