Because of the reasons for work, I came into contact with JDO. At that time, I was very interested in this novel thing, so I was able to translate the included JDO guide while familiar with Kodo.
This translation is not an authority. On the contrary, it can be said that it is not mature. After all, I am not a professional translator, and the original purpose is just through the translation of knowledge. If you decide to learn JDO, I suggest you look at this translation In the English tutorial. After all, I didn't have a lot of pictures.
Don't blame my sense of responsibility. Because JDO's mastery is really difficult, then I have a new task. So I put the translation and tutorial. Waiting for the work is not so nervous, I will make the translation.
However, there is also a question in my heart. In the new EJB specification, JDO will be merged into the EJB framework. Is it necessary to learn JDO?
Oh, the world is not waiting for me. Take a look at its realization, understand some design ideas, why not a fast?
