Before D2W came out I once created 5 CRUD apps with the older
WebObjects wizard in 1/2 hour with three other managers arguing in my
office over the look & feel of said CRUD app. It was one of the
things that prevented us from migrating to another environment.
Unfortunately, the J2EE zealots did ultimately carry the day, some two
years later.

Hi, David,
I think the comparison between CSS and D2W is imaginative and accurate
as far as it goes, but badly undersells D2W.
Without comparing it to CSS, I think its power can be understood by
the following statements:
* If a legacy database exists, or we create a new database, we can
use WebObjects' EOModeler that uses the database (and the answers to a
few simple questions in its wizard) to automatically derive an EOModel
for that database that maps its tables, columns and attributes to a
corresponding set of Java classes, instance variables and types with
no programming on our part whatsoever. This typically takes an
experienced WO developer a very few minutes to create an EOModel that
doesn't seem very useful, but...
* We can create a new D2W Java project in Xcode directly derived
from the EOModel we just generated to completely create a web based
CRUD (Create, Read, Update, Delete) editor to edit any attribute(s) in
any row in any table in that database. This typically takes an
experienced WO developer a very few seconds with no programming at
all.
The result is a new, scalable, Java, web based, graphic interface to
our database typically created in less than 5 minutes from start to
finish that may be enhanced and customized as we desire. This is about
as RAD (Rapid Application Development) as you can get on the web
today. More importantly, the resulting application is an enterprise
class web server application rather than some cheap toy that will
break down under load.
Add the Project Wonder frameworks (as I understand) and it not only
becomes robust, but comes with methods that are already available to
do most anything one wants to do on the web. To substantiate this last
claim, simply Google on the two phrases "Anjo Krank" and "Project
Wonder" to see the number of questions that have hit this list in
which Anjo's answer was "We've already done that in Project Wonder."
Though some of us may tire of hearing that phrase from Anjo, he's
provided a valuable service to the community to raise awareness of the
incredible richness of Project Wonder when paired with D2W (for which
it was originally created).
AND IT'S ALL FREE (under the appropriate circumstances).
Regards,
Jerry

After reading all the Direct to Web stuff I could get my hands on, I
was trying to describe to my boss why we need to be looking at it and
moving towards it. The metaphor I came up with was that D2W is like
CSS for objects. I think that sort of describes its power, but I
would be interested in how others make the argument for (ER)D2W to
non-programmers (or programmers for that matter!).
