使用Java的数据库应用程序中的设计模式（Java EE / Java SE）
我一直在阅读*一段时间，现在我只是在想一个问题。我20岁，目前在我的家乡（罗马尼亚克卢日 - 纳波卡）入读IT大学。足够介绍：D。
I've been reading * for quite a while now and I'm only now building the nerve to ask a question. I'm 20 years old and currently enrolled in college in IT here in my hometown (Cluj-Napoca, Romania). Enough for introductions :D.
基本上我有我的小软件公司提供Book-keeping appz。他们（可怕的）用Delphi编写，我想从头开始，用Java编写。我以前在Java方面没有什么经验，但是我想学习，我选择了Java，因为平台提供了便宜和优质的工具。
Basically I have my little software firm that provides Book-keeping appz. They're (horrifyingly) written in Delphi and I want to start from scratch and write them in Java. I've had little experience with Java in the past but I want to learn and I've chosen Java because of the cheap and quality tools the platform offers.
现在可以您可以指出我正确的方向，在哪里可以找到一些完整的文档（书籍，网站，博客等），以获取正确构建数据库应用程序的一些信息，包括使用DB的设计模式（我的选择是PostgreSQL，并已经订购了一本书）和Java。我知道我第一次无法得到它，但至少让它接近正确。
Now could you please point me to the right direction as where could I find some complete documentation (books, web-sites, blogs etc) as where to get some info on properly building database applications including design patterns with DBs(my choice is PostgreSQL and have already ordered a book) and also Java. I know I won't be able to get it right the first time but at least get it close to right.
谢谢
首先：欢迎： - ）
有很多优秀和免费的资源覆盖Java作为一种语言（例如 wikibooks ），Sun的参考文档也很全面。一旦了解了语言的基础知识，我认为它可以深入挖掘数据库应用程序和模式的深度。如何？
There are a lot of good and free resources covering Java as a language ( e.g. wikibooks ), and the reference documentation by Sun is also quite comprehensive. Once you have understood the basics of the language, I think its time to dive into the depths of database applications, and patterns. How?
首先，您应该尝试构建一些简单的数据库方案，操场 - 方案从我可以看出来有所帮助。想象一下一个图书馆，并试图建模。它不需要很长时间，你会学到很多。
First of all, you should try to build some simple database schemes, "playground"-scenarios are helpful from what I can tell. Imagine e.g. a library and try to model that. It doesn't take long yet you will learn a lot.
对于模式，我一般认为它们是一个指导，像你可能会纳入的MVC模式。不要强迫自己首先使用它们，尝试一次理解一个，并重构你的代码，使其中有一些模式，而不是首先写入模式。
For patterns, I generally think of them as a guide, like the MVC pattern which you will likely incorporate. Don't force yourself to use them all in the first place, try to understand one at a time and refactor your code to have some pattern represented there rather than writing to a pattern in the first place.
所以，祝你好运！ （当然，一旦你被卡住，请问！）
So, good luck! ( and of course, once you're stuck, just ask! )
