| Sure Chuck,
The first time when I learn EF I thought that they based the development on EOF.
As with EOF you have many connector for different Data bases. There is a graphical designer to design you model or you can reverse engineering your database or ya can define the model by code, There is support for all kind of relationships: to-one, to-many, many-to-many They support Spatial types. You can integrate with XAML thru bindings as is made in cocoa There are way to define the relationships configurations (required, optional, cascade delete, etc.) There is a context similar to EOF context You can navigate the relationships in an Object oriented way You can specify the attributes to check the concurrency There is a way to define the resolution of concurrency conflicts To search you can use LINQ, raw SQL, by primary key, store procedures, etc. They use lazy loading for relationship (proxy) Thera is support for migrations (versioning) Of course, it is very well integrated with many other MS technologies
Well, I think that everything that I used in EOF is there (I don’t mean that all that is in EOF is in EF, just all that I needed).
Well, is what I remember at this moment but if you have something specific in mind let me know and I'll check it to see if there is something similar in EF.
I’m not working with this technology anymore, not because I don’t like it, its pretty good and you can find tons of info, books, code examples, etc. but for a new big project (big for us) we decided to use _javascript_. We decided after many discussions what is the best options for this project and we are convinced that JS is the best option for us.

Daniel.
Hi Daniel,
Can you tell us how Entity Framework measures up to EOF? Is it better in some areas? Is it missing features in other areas?
Thanks,
Chuck

Hi all,
I would like to share my experience with WO.
We have developed many systems with WO, some of them was for a big telephone company here in Mexico. After some changes in the IT department in this company they decided to change all the system developed with WO. They call HP, MS and many other companies
to get a proposal for the change of this systems, after many meetings with these people they decided to leave the system because the cost and time of development was out of they budget (we have developed that systems in a very short time and the cost was small
compared with the other companies because all the facilities of WO). The system survived some time but finally the get the money and changed the systems.
For a long time I was afraid to leave the WO dev tools. I have developed many applications and I can’t find any thing close to this tools. But for customers decision we need to look for new tools and luckily we have found tools that let us forget of the
awesome of WO.
We have developed with Entity Framework, XAML and C#, VisualStudio, not perfect but for many systems has everything that you need.
Other tool that we have used for a small (tiny) projects is Groovy on Grails. Fast, easy to learn, develop and deploy.
Now we are very excited using the new _javascript_ tools like SproutCore, Ember, nodeJS, MongoDB, etc.. The things that you can achieve with this tools are amazing. Most of the people behind SproutCore and Ember have worked for Apple.
Before we found this platforms we lost projects because the lack of enough developers to support the WO systems and the stories in Internet that said WO is dead (We know is not dead but is very hard to convince the other people).
I'm still using WO for internal and personal projects, but now I’m migrating everything to the _javascript_ world.
Regards,
Daniel.

Hello,
this is not a technical inquiry, more a temperature check on the business side of WebObjects. It is my impression that at least in Germany, after the 2008/2009 crisis the market for WebObjects-projects has really been down a lot. I have been looking hi and
lo for opportunities to work with WO again, but apart from self-initiated projects there was nothing going on.
Is this perception limited to Germany or is it even just me? Are there any project marketplaces for WO that I am not aware of? How much of a future would you guys think WO really has?
Kind Regards,
Jürgen
A
(sad) success story:
I
have an existing customer (large world-wide operating corporation) with some very old WO apps which I maintain. They also have a small app based on D2W with the old neutral look. This app has been created by some JEE folks who had no clue about WO. The app
primarily generates product related PDF files from text-snippets stored and maintained in the database. Maintenance of the data is done by the D2W application. The JEE folks were not able to properly use WO and had big performance problems with PDF generation.
So they build a library where they access the database with raw JDBC calls (!!) and have an instance of the app running on a dedicated PC somewhere in a corner so to not block the interactive parts. I have since taken over this application and first of all
thrown out everything JDBC related. Redesigned the database structure (they had most of the logic in the data instead of in the databse structure), implemented proper management of the product related spec sheets, and re-
Unfortunately
corporate IT wants to take over the project and kill it (it doesn't fit in with their strategy), customer is furious but the decisions are made elsewhere. We'll see.
Another
success story:
I
am a part time teacher and have tried to cover the module "object oriented development of multiuser database applications" using Wonder. Fortunately the school has given me quite some slack. One of my students from last year (I am currently teaching this module
the 3rd time) has introduced Wonder to his employer and could setup a new project! As far as I know both my former student and his boss are happy. YEAH!
It's
difficult finding WO work. Wherever Java is wanted JEE/Hibernate/Spring/JSF/younameit is asked for, or then its dot-net. No way to do anything with WO. I was able to be introduced privately to an older rather rich person who has a lot of his money stuffed
away in real estate. For him I could develop a finance tracking application for his investments so that his daughter will be able to maintain the finances once he is gone (which I hope will not be so soon....). That's a modern look ERD2W application hosted
by my company. Customer is happy so far and plans for more.
But
I agree, it is very difficult finding WO work. It's not the tools, it's not WO, it's probably not even the closed-source thing, it's just the buzzwords that are completely missing. Nobody in the Java world is even considering something other than JEE and friends
because "that's the standard".
Sad
but true.
