调用session.save()方法，hibernate一定会发出insert语句吗？谈谈你的理解
调用session.update()方法，hibernate一定会发出update语句吗？谈谈你的理解
配置了lazy=”true”一定会实现懒加载吗？
谈谈你对Hibernate实体类中的数据库标识与数据库主键之间关系的认识？
谈谈你对Hibernate关联映射与数据库外键之间关系的认识？

save不一定会马上就执行，自动提交就会马上执行，选择的是手动提交事务的话，要等统一提交执行，update一样。
不一定会懒加载。看具体情况，
Hibernate实体类中的数据库标识与数据库主键之间一般一一对应

数据库在开发时最好设定外键，以保证数据的完整性等，实际发布后其实不需要设置外键，
所有的数据对象关系都应该在Java代码中做好约束与判断，
数据库上设置外键关联，主要为了保证数据的完整性，简单的说就是学生表里面删除一个学生后，需要把这个学生在成绩表中的信息也删除，否则会出现一个不存在的人有成绩 参考技术A save不一定会马上就执行，看你的设置，默认是等待所以操作都完成了，事务已提交，才执行，update一样。
不一定会懒加载。看某些情况。
数据库外键其实不需要设置，所有的数据对象关系都应该是在Java上体现了，数据库上设置外键关联，我数据库知识浅薄，不知道主要用途

这段话麻烦高人翻译一下，谢谢！

我需要出国学习，所以要填一份表格，其中有个问题是问“你是如何希望你的训练和你将来的事业联系起来”，我是学临床护理的，别人帮我弄了，不是很好，想要高人帮我翻译下，谢谢了！
内容：
我是一名肿瘤学护士，肿瘤疾病是比较复杂的疾病，为了病人更好的康复与治疗，想扩大自己的护理专业知识及肿瘤学相关知识面，特别是心理学方面，通过学习与训练，更好的为病人贡献与服务，减轻病人的痛苦，促进健康。

就是这段话，麻烦翻译一下，谢谢了！~

个人认为：翻译这段最好调整语序，这样更有逻辑性。
