    v4 v5  
    1717   * HTML5 讓事情更複雜，允許更多攻擊，包含本地端的資料庫。

     19   * Big Data -> Medium Data 都需要
     20   * Cloud Computing - Scale Free

     23   * 不要用 Spreadsheet 的想法看待 HBase, 或許可以用 Tag 的想法去看待它。
     24   * HBase 跟 BigTable 都是 CP 架構(注重 Consistancy 與 Partition Tolerance，根據 CAP Theorem 因此無法確保 Avaibility，寧可服務中斷也要資料正確！！)
