請看到這第一： Good Coding Practices用的EntityFramework使用事務從商業邏輯層
所以，這是我設計的。
- 網站 2.Business邏輯層 3.DALFacade（我們使用dalfacade隱藏數據訪問，因爲我們使用2家不同的商店，SQL和DB2） 4.DAL
在DAL我們使用工作單元模式和存儲庫模式。 1.這裏最大的問題是：如果下面的代碼對於從業務邏輯創建的事務運行正常。
Page:
public partial class NewBonusRequest : System.Web.UI.Page
{
#region Constructor and Instantiation of Business Logic
/// <summary>
/// Property that holds the Business Logic type to call methods

RequestBL = RequestBL;

// Call to other DALCFacade methods that insert data in different tables
// OtherObject.Save(otherobject)

}
