Do other languages have such a concept as JDO ? What Design Patterns do typical implementations use ?
I've been hearing for sometime about JDO and anxious to try it. I'm hooked on JDBC's simplicity for now.
Thanks to the authors for submitting to this forum !

C++ object databases provide transparent persistence, though they never attained the level of portability and transparency that we got with JDO. JDO is an order of magnitude improvement over these older technologies, including the ODMG Java binding. Craig and I should know too, Craig served as the ODMG Java Chair and I was the ODMG Java editor.
I have heard rumors that Microsoft was developing something modeled after JDO for C#. Also, one JDO vendor, FastObjects, has announced plans to support C# and I suspect it will be very similar to JDO.

You say you are hooked on JDBC?
You should try writing a small application with JDBC and see which you consider simpler... ;>

Well, my space isn't very complex - usually a JSP or servlet with a select statement against oracle. I am intrigued. Other posts say that with heavy CRUD that JDO is the 'thing to do'. ALL I DO is CRUD ( usually web-based db table admin apps), so I must do some more reading on this JDO thing.
Thanks !

Chapter 1 of our JDO book is available online and walks through a small simple example that provides each of the CRUD operations and how it is done in JDO. Read this and you should get a good feel for what it is like to use JDO and what the rest of the book is like.
