          cosmos框架主要用來做中小項目開發，丟棄了傳統的SSH架構，利用純的Servlet+JDBC實現數據庫操作。開發Web項目，可以實現無需寫Java代碼，
而實現業務邏輯，并且由于不需要寫Java代碼，因此，可以不需要重啟和重新部署項目，就可以直接測試，達到了開發->刷新測試的水平。根據目前多
個項目的應用實踐看來，基本上可以提高一倍到2/3的開發時間，而且性能比起SSH架構還要高，框架還要更加輕量級。因此，這個框架還是比較能夠體現敏捷
開發的思想的。
          

          
由于框架摒棄了Hibernate的O/R Mapping工具，因此有一個比較大的問題就是關于數據庫移植性的問題，但是，根據公司對于中小項目的經驗，一旦客戶要移植數據庫，幾乎就需要重新實現業務邏輯了，因此，對于中小項目來說，這是一個不錯的選擇。
          

          
——————
          
官方介紹：
          

          

          cosmos框架
是一個對于底層數據庫、Web服務、JNDI等進行統一界面封裝的框架，提供統一的調用接口，并采用命令設計模式，將所有需要調用的命令放置到數據庫（或
者其他域）中去，從而可以改變傳統的j2ee應用調試的流程：開發-部署-測試或者開發-部署-重新啟動-測試，達到像PHP、PERL那樣的開發
->測試的模式。有效地提高了開發速度。 
          

          由于其拋棄了所有的中間層次，包括像Struts、Spring、Hibernate這樣的框架，調用數據庫應用直接用JDBC的方式進行，因此有效地提高了運行性能。
由于開發的代碼可以完全放置到數據庫中，因此，可以比較容易地實現共享開發，從而有效地調動起開發人員的積極性。
在cosmos框架中開發一個數據庫應用的流程是：開發SQL語句或者存儲過程或者函數；然后開發JSP頁面進行展示；最后測試結果。完全地省略了開發Java代碼的過程，因此，有效地提高了開發速度。
cosmos框架是一個能有效地應用于中小項目的框架，可以供開發人員快速建立原型，從而實現敏捷開發的目的。
在框架中還包括權限和認證的部分框架，因此，用戶可以簡單地實現用戶認證和系統權限的功能。

The Asian focus has helped propel Google up the charts in The Wall Street Journal Asia's reader survey of Asia's most-admired multinationals. Google grabbed the No. 1 spot in the featured category, 'Innovative in Responding to Customer Needs.' It is the second survey in a row Google has held the top spot as an innovator, a category that asks readers to tell us which companies they consider best at bringing new products and services to the market as well as at employing sophisticated customer service.

Ext.fly(A) is null 開始的時候一直提示這個錯誤~
          
后來發現firebug一直提示這個錯誤,每次調試的時候清空下cache比較好~~~

          今天數據庫直接超過4G，查了下原來是索引問題，一個索引占了2G大小~~
