Wrong. Transactions allways happen. An insert/update causes the db
adapter in question to register itself for transactions, but ZODB itself
won't inflate unless an object
Thanks Leonardo,
I was confusing the two. The encapsulation, yes that makes a
lot more sense.

No, and RDBMS update or insert does *not* cause the zodb to

To everyone who replied to this thread, I give a hearty
congratulatory "Thank you". They have decided to allow me to
mock up the app in Zope and prove it's worthiness. I'm already
halfway done with the first 2 modules. ;-)

Thanks, that's an important distinction. Not just one
transaction item, but all the items you group into one
'business transaction' within the Zope application. Meaning
(not that it's the case here) multiple different database
writes, yes? Powerful stuff.

Dirk,
One more quick question about application/business logic in one
place and layout in another.
Looking at ZPT, I still see expressions and condition
statements in the Templates themselves. That's not really
separation, it's just making it work with HTML editing tools.
I'm curious is
Thanks Lennart,
There is OO php now, which they seem to enjoy. The
audited security is something I believe is big win. The
quickness and efficiency of Zope Corp's (still calling them DC
in my head) Zope security patching is outstanding. The
community really shines there.

Dirk,
Thanks for that. By 'separation' I'm assuming you mean ZPT,
correct? I'm new to that, but the virtues seem to be simple

Curiously, if there are prepackage scripts for both, and

That's a big win for Zope when dealing with inventory and

I think that's a big part of it. Using something that's
already documented that has many features of a 'web app' built
in already, vesus scripting those. But there are a lot of
prepackaged scripts for Calendars, and database connections,
shopping carts, etc... for PHP. So there's got to be

I have only minor experience with PHP so this may be ignorant, but isn't
programming a web application with PHP scripts more comparable to
programming such an application with Python scripts? If PHP scripts are
handling HTTP requests directly, that can also be done with pure Python
scripts.
I am not a PHP guy by any means, but I imagine having to run an
extra server (Apache, Postgres vs Apache, Zope, Postgres) means
there is another server process to watch, manage,
start/restart. You don't have to do those things with PHP
scripts.
Perhaps someone with experience with a larger P
