oracle的体系太庞大了,对于初学者来说,难免会有些无从下手的感觉,什么都想学,结果什么都学不好,所以把学习经验共享一下,希望让刚刚入门的人对oracle有一个总体的认识,少走一些弯路。
一、定位
    oracle分两大块,一块是开发,一块是管理。开发主要是写写存储过程、触发器什么的,还有就是用Oracle的Develop工具做form。有点类似于程序员,需要有较强的逻辑思维和创造能力,个人觉得会比较辛苦,是青春饭J;管理则需要对oracle的原理有深刻的认识,有全局操纵的能力和紧密的思维,责任较大,因为一个小的失误就会down掉整个,相对前者来说,后者更看重经验。


    因为数据库管理的责任重大,很少公司愿意请一个刚刚接触oracle的人去管理数据库。对于刚刚毕业的年轻人来说,可以先选择做开发,有一定经验后转型,去做数据库的管理。当然,这个还是要看人个的实际情况来定。

二、学习方法
    我的方法很简单,就是:看书、思考、写笔记、做实验、再思考、再写笔记

    看完理论的东西,自己静下心来想想,多问自己几个为什么,然后把所学和所想的知识点做个笔记;在想不通或有疑问的时候,就做做实验,想想怎么会这样,同样的,把实验的结果记下来。思考和做实验是为了深入的了解这个知识点。而做笔记的过程,也是理清自己思路的过程。

    学习的过程是使一个问题由模糊到清晰,再由清晰到模糊的过程。而每次的改变都代表着你又学到了一个新的知识点。

    学习的过程也是从点到线,从线到网,从网到面的过程。当点变成线的时候,你会有总豁然开朗的感觉。当网到面的时候,你就是高手了

    很多网友,特别是初学的人,一碰到问题就拿到论坛上来问,在问前,你有没有查过书,自己有没有研究过,有没有搜索一下论坛?这就叫思维惰性。由别人来回答你的问题,会让你在短时间内不费劲地弄懂这个知识点,然而通过自己的努力去研究它,不但会更深入的了解这个知识点,更重要的是在研究的过程会提高你解决问题和分析问题的能力。总的来说,没有钻研的学习态度,不管学什么东西,都不会成功的。

    当然,初学的人很多时候是因为遇到问题时,无从下手,也不知道去哪里找资料,才会到论坛上提问题的。但我认为,在提问的时候,是不是可以问别人是如何分析这个问题?从哪里可以找到相关的资料?而不是这个问题的答案是什么?授人以鱼不如授人以渔。

    下面我讲下我处理问题的过程

    首先要知道oracle的官方网站: 这里有oracle的各种版本的数据库、应用工具和权威的官方文档。其次,还要知道这里是买了oracle服务或是oracle的合作伙伴才可以进去的,里面有很多权威的解决方案和补丁。然后就是一些著名网站:asktom.oracle.com , 。这里有很多经验之谈。

    遇到问题了。如果是概念上的问题,第一时间可以找tahiti.oracle.com,这里会给你最详细的解释。如果在运行的过程中出了什么错误。可以去metalink看看。如果是想知道事务的处理的经验之谈。可以去asktom。当然。这里只是相对而言。
