跟我一起学extjs5(33--单个模块的设计[1建立表和bean])

现在开始进入这个系统的第一个核心部分，就是如何对模块的功能进行设计。请看下图，一个最简单的模块包括的内容有：模块属性，字段属性，列表定义和表单定义。

在上面的定义中，一个模块可以有n个字段组成，可以有若干个列表方案和表单方案；每一个列表和表单可以有若干个组组成，每个组下面又有若干个字段。这样的设计也符合这个教程的前20节中设计出来的功能。现在要做的就是把这些功能做成前后台交互的。

先开始模块字段和列表方案的定义。以上各个方案的定义也都是放在数据库中的，因此先要建立好各个表和java bean。

建立模块字段的表 _ModuleField。

CREATE TABLE [dbo].[_ModuleField](
	[tf_fieldId] [int] NOT NULL,
	[tf_moduleId] [nvarchar](10) COLLATE Chinese_PRC_CI_AS NOT NULL,
	[tf_fieldOrder] [int] NULL,
	[tf_title] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
	[tf_fieldName] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
	[tf_fieldType] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
	[tf_fieldGroup] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_fieldLen] [int] NULL,
	[tf_propertyTypeId] [int] NULL,
	[tf_isHidden] [bit] NULL,
	[tf_isReadonly] [bit] NULL,
	[tf_isRequired] [bit] NULL,
	[tf_isDisable] [bit] NULL,
	[tf_isUserDefine] [bit] NULL,
	[tf_userDefine] [nvarchar](max) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_allowGroup] [bit] NULL,
	[tf_allowSummary] [bit] NULL,
	[tf_otherSetting] [nvarchar](max) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_defaultValue] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_remark] [nvarchar](max) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_fieldRelation] [nvarchar](20) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_newNeedSelected] [bit] NULL,
	[tf_showNavigatorTree] [bit] NULL,
	[tf_DBFieldName] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_DBformula] [nvarchar](max) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_divisor] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_denominator] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_allowNew] [bit] NULL,
	[tf_allowEdit] [bit] NULL,
	[tf_allowInsertExcel] [bit] NULL,
	[tf_allowEditExcel] [bit] NULL,
	[tf_haveAttachment] [bit] NULL,
	[tf_isChartCategory] [bit] NULL,
	[tf_isChartNumeric] [bit] NULL,
 CONSTRAINT [PK___ModuleField__4D94879B] PRIMARY KEY CLUSTERED 
(
	[tf_fieldId] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY],
 CONSTRAINT [_ModuleField_ix1] UNIQUE NONCLUSTERED 
(
	[tf_moduleId] ASC,
	[tf_title] ASC,
	[tf_fieldName] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

	public _ModuleField() {

	}
    //getter and setter
}

在上面的这个java类中，对模块字段设置了许多的属性可供定义，这个可以根据软件的扩充自己进行加入和处理。在这个例子中，我只能讲一下最简单的一些属性的应用。

建立模块列表方案表，列表方案分组表和列表方案分组的字段表。
