CR 不难，但数据整合去支持CR 或其他BI 不易，工作稳定

Any report tool are similar simple, they are just for fianl display.

The diffuclt task is to provide good data for those reports. These are in the categoty of Data warehousing, data mart, BI, even data minig .....

Just becasue the report writer support normal production, rather rhan developement, the jobs are stable as the business goes.

The hourly pay (to person) around $35 through $250 depends your real skill on data processing, not end reports. In most cases, I charge my clients by case rather than by hour. I feel it is fear to both. The rate is same applied to cases from China.

Any report will directly related to business decision,
your clients will depend on you if you have good skills
in but tech (really can do) and personal (never expect free lunch).

As for how to master the data warehousing issue, I think any one who can understand Chinese history, who can do it.

司马迁：史记，最好的data warehousing 范例；
司马光：资治通鉴, 最成功的基于data warehousing的DSS；
纪晓岚，四角号码检字法，人类最早的语言数字化的范例；

如果朋友爱读兵书，孙子兵法等是极好的data mining 实例。

用这样的中华文化指导你的学习与工作，老美老印永远抢不走你的饭碗（非我族类，其心必异。心异则无诚，无诚自五果）。

祝有中华文化的朋友大吉大利。
