Mvc.Ext.Net项目架构（二）

　　不好意思我的语文是体育老师教的所以.....。

　　我每次需要和数据库交互的时候需要先写一个接口在IDAL里面，然后在DAL实现代码并做一些逻辑处理，web层直接调用BLL中的方法来实现数据的持久化操作。整个系统对于某些表的实体映射是有的但是在最主要的档案数据和文件数据中就没有映射，因为这个表的字段是可以通过项目人员来自行配置的也就是说我只需要设置下面这张表

CREATE TABLE [dbo].[Arch_Fields](
[Id] [int] IDENTITY(1,1) NOT NULL,
[FId] [int] NOT NULL,
[FieldName] [nvarchar](50) NOT NULL,
[FieldCName] [nvarchar](80) NOT NULL,
[FieldType] [tinyint] NULL,
[IsMust] [bit] NULL,
[IsPhyFld] [bit] NULL,
[IsSystem] [bit] NULL,
[DisplayOrder] [int] NULL,
[AutoFormula] [ntext] NULL,
[Format] [varchar](50) NULL,
[FieldTop] [int] NULL,
[FieldLeft] [int] NULL,

[FieldLength] [int] NULL,
[ListVisible] [bit] NULL,
[ListOrder] [smallint] NULL,

我的关键数据都是和目录有关系，所以点击目录的时候会自行去查找项目人员自行配置的列表数据然后显示数据，或者选择数据时增删改数据，下图为一个实例

不好意思我的代码太乱，让各位大虾见笑了，如果有好的意见请多多指点。未完待续..求大虾能对我的框架不管是后台和前段都能给我提出宝贵的意见，再次先谢谢
