  * 此外也提到 IDC 報告裡，說明了預估未來 2012 年近五成的雲端運算會花在 Bussiness Application 上。

{{{
戰場改變，生活習慣也開始改變，都是因為雲端運算(cloud computing)越來越貼近人群，
也因為資料量的龐大，開始不一樣的改變，以工程師的角度 programming 的方式開始不一樣，
機器的 maintain也開始不一樣，以產業經營者的角度來看，獲利方式也開始不一樣。

function programming非常重要....
必須要自己先做方程式分解，先把需要計算的先算好，然後再組合....
所以想好公式，思考好key是什麼，分次計算，在集合起來。
