Is an OR mapping tool helpful?

[Donghyeok Kang]

Hi, all...

My project team are considering an OR mapping tool.

I have looked into some open source projects developing OR mappings.

I don't think it's easy to use them at all.

Some of them seems to be more complex than entity beans of EJB.

I wonder if an OR mapping tool is really helpful or useful in developing.

Please give me an advice on OR mapping.

Thanks in advance.
