做global项目时，会要求详细文件管控，对代码同样如此，所以对Oracle Object所有的对象都要有命名要求和代码规范

以下对Oracle的对象和文件做一个简单介绍

在DBA对程式做instance搬迁时，一个良好的代码管控机制，会减少很多不必要的麻烦

国内项目，可能对代码文件的管控不是太复杂，主要是由具体developer进行控制，所以每个developer对应的代码风格，就会影响整个项目

所以在项目开始，对一系列的代码标准，文件命名方式进行控制，对项目成果有很大的帮助

特别是当一个项目人员的流动率超过一定幅度时，代码说明和文档记录非常重要，不至于一个developer的离开对项目的进度有非常大的影响
