怎么回答这个问题: “xx 大哥/大姐/大神, 我是一个码农, 我想转行到数据这方面, 我该怎么做?” (PART 1)

被人问了N多次了, 所以决定试着系统的回答一下。我抛砖引玉一下,粗粗写一下东西, 希望这里的专家们给我点反馈,我会加到这篇文章里,慢慢完善,先提前谢谢大家了!
 
首先, 这个问题得分几步答:
1.    传统“数据行业”里到底都有什么不同的职位?
2.    每种职位都需要什么skills, technical knowledge和personal qualities?
3.    怎样得到和发展这些技能, 达到成功转行?
4.    【Bonus】和大数据相关的职位又是怎么一回事儿?
 
今天PART 1 就是回答第一个问题 - 数据行业大了,你到底想干那行儿啊?
 
以我一点愚见,数据工作大概分两类,一类是Technology based, 另一类是Business based (不包括Research/Academic一类的),当然如果你在很高端的职位或者在很小的公司里, 会有很多overlap, 你得懂technology也得懂business. 最终, 都是给end users (managers, operation teams and customers)服务.
