业务模型管理中所涉及的业务模型，业务模型的属性，业务模型的视图都是可以通过权限设置来实现数据的行（视图），列（属性）权限管控。业务模型是整个EDP平台的核心基础，数据的查询、新增、修改、删除、行列权限都是通过业务模型来实现的。
按分类管理系统内各个业务模型，对应系统中各个业务对象。
管理业务模型分类。
新增业务模型
编辑业务模型
业务模型代码生成
表设计文档模板，可以包含多个表结构设计
创建业务模型类，继承基类ModelPermissionBase。定义好的业务模型可以在上述的业务模型管理功能中进行管理，实现数据行、列权限的管控。

[ModelEnitity(TableName = "t_school_student", KeyName = "ID")]
TableName：表名

ColumnName：字段名称
IsRequired：是否必须，用于验证属性值是否必须有值

查询对象是用来实现业务对象的查询，通过属性来设置查询条件。需要继承QueryModelBase基类。
using System;
namespace School.Model
{
using EDP.Common;
using EDP.Common.Model;
///
/// 学生信息查询对象
///
[QueryModel] //标记类的查询对象特性
public class StudentQueryModel : QueryModelBase //继承QueryModelBase
{
///
/// 姓名
///
[QueryModel(Operator = QueryOperator.like, ColumnName = "Name")]
public string Name { get; set; }
///
/// 性别
///
[QueryModel(Operator = QueryOperator.eq, ColumnName = "GenderId")]
public int? GenderId { get; set; }
///
/// 校区
///
[QueryModel(Operator = QueryOperator.eq, ColumnName = "CampusId")]
public string CampusId { get; set; }
///
/// 班级
///
[QueryModel(Operator = QueryOperator.eq, ColumnName = "ClassId")]
public string ClassId { get; set; }
///
/// 班级全编码
///
/// ClassFullCode like '值%'
[QueryModel(Operator = QueryOperator.likeRight, ColumnName = "ClassFullCode")]
public string ClassFullCode { get; set; }
///
/// 编号姓名关键字
/// Number和Name都进行like查询
///
/// Number like '%关键字%' or Name like '%值%'
[QueryModel(Operator = QueryOperator.like, ColumnNameList = "Number;Name")]
public string NumberNameKeywrod { get; set; }
///
/// 分页对象
///
public PageModel Page { get; set; } = new PageModel();
}
}
[QueryModel(Operator = QueryOperator.like, ColumnName = "Name")]
Operator：查询操作符（=、>、<、>=、like等）
ColumnName：对应业务对象的属性（实体属性，扩展属性），只要是默认查询SQL中包含的字段都可以作为查询对象的属性（查询条件）
详见示例项目StudentBLL.cs
业务模型属性验证
var verify = item.Verify(keyValue);
此处通过Verify()方法验证业务模型各属性值，通过属性验证标记（IsRequired，MaxLength, Regex）进行验证。
业务模型新增
item.Create(db);
item.ValidateSQL = string.Format("where not exists (select 1 from t_school_student where Number = '{0}')", item.Number);
result = item.InsertModel(db);
通过业务模型Create()方法创建当前实体对象。
通过ValidateSQL属性值确保不会有重复的Number值插入到数据库。
调用InsertModel()方法新增业务模型数据。
item.Modify(keyValue, db);
item.Number = null; //编号不能修改
result = item.UpdateModel(db);
通过业务模型Modify()方法修改当前实体对象。
调用UpdateModel()方法修改业务模型数据。
ResultModel ret = new ResultModel();
ret.Content = new StudentModel();
ret.KeyValue = keyValue;
ret.Content.ID = keyValue;
ret.Content.Query(db);
使用统一的返回对象 ResultModel。
实例化ret.Content并设置操作的主键值ret.KeyValue = keyValue。
设置查询的主键值 ret.Content.ID = keyValue。
调用业务对象Query()方法 ret.Content.Query(db)。
执行Query()查询后，根据权限设置给ret.Content赋值。
ret.Content.AccessPropertyList中返回有权限的属性名称。
ResultModel> ret = new ResultModel>();
ret.Content = new List();
ret.Content.Query(queryModel.Page, queryModel, db);
ret.Page = queryModel.Page;
使用统一的返回对象 ResultModel>。
实例化 ret.Content = new List()。
调用业务对象Query()方法 ret.Content.Query(queryModel.Page, queryModel, db)。
queryModel为查询对象StudentQueryModel的实例。
执行Query()查询后，根据权限设置给ret.Content赋值（有权限的数据集合）。
ret.Content[0].AccessPropertyList中返回有权限的属性名称。
StudentModel item = new StudentModel();
item.Id = keyValue;
item.DeleteModel();
实例化StudentModel。
设置主键值 item.Id = keyValue。
调用业务对象DeleteModel()方法 item.DeleteModel()。
