Oracle数据库对很多开发人员而言，基本就只是一个存储数据的仓库，只不过这个仓库功能非常强大，额外提供了很多好用的功能，需要的时候会用就好，不会纠结于某个细节。而对很多DBA而言，正好相反，喜欢沉溺于某些细节上，对某些小知识点对应的原理理解的非常透彻，但却往往很少会站在开发层面认识Oracle。
本文旨在构造一份相对较全面的测试数据，对开发常用的对象都模拟创建一份测试用例，DBA就可以直接拿去做一些基本测试。
环境：Oracle 11.2.0.4
初始化测试数据的脚本主要包含了如下内容：
脚本：initData.sh
#!/bin/bash
#name：initData.sh
#function：to initial data for test.
#usage: oracle用户登录，执行 sh initData.sh > /tmp/initData.log
#logon database
sqlplus -S / as sysdba <<EOF
