 在本節我想與你們與分享一下，我所將要作的權限系統的架構和數據庫的表的設計。請各位大神們對我項目中設計的不足之處進行指導，讓我得以更好的寫完它，留給須要它的人。sql

個人項目架構以下圖所示：數據庫

如上圖所示，在數據訪問層，我採用了抽象工廠的方式，來對數據訪問層和業務邏輯層解耦，固然若是你想更高大上一些，能夠用第三方的框架，好比Spring.Net ，Autofac來實現。解耦的好處在於能夠方便的切換數據庫，當數據庫變動時，只需換一下對應的數據訪問DAL就行，本系列中，我所採用的是SQLServer。寫到這我想在以下這個大數據時代，MongoDB其實也是不錯的。後面有機會，能夠開一個MongoDB的專題和你們一塊兒來使用一下MongoDB學習一下它。對於抽象工廠來實現業務邏輯層與數據訪問層的解耦實現代碼以下，主要用到了反射，面向接口編程。編程

配置：緩存

全部的訪問數據庫的操做都用接口來約束：app

    {
        int Add(T model);

        int UpdateDel(string ids, bool isDel);

        int Del(string ids);

        int Update(T model);

        DataSet GetListByProc(string procName, System.Data.SqlClient.SqlParameter[] paras);

        DataSet GetModel(string Id);

        DataSet GetList(string strWhere);

對於，業務層到UI層之間的解耦，我沒有按架構圖中的去實現，我覺在通常中的項目中沒有這個必要，爲了簡化 ，我因此省去了，若是你想加上，徹底能夠按抽象工廠的方式加上。以上就是我對整個項目的架構上作的一個說明。接下來咱們再看看我數據庫的設計。大數據

 

   權限的細化顆粒度到各頁面的按鈕。對於以上的架構和表設計，若是有什麼好的建議能夠給我留言。下一節，咱們將完成主頁面的主休框架和登陸驗證。
