///用于定义和映射数据库记录的根类
//-从TOrm继承一个类，并添加已发布的属性来描述
//表列（请参阅TPropInfo for SQL和Delphi类型映射/转换）
//-可以使用
//FillPrepare（）和FillRow（），或具有TOrmTable或JSON数据的FillFrom（）
//-这些已发布的属性可以转换回UTF-8编码的SQL
//具有GetSqlValues或GetSqlSet的源代码，或具有GetJsonValues的JSON格式
//-BLOB字段被解码以自动释放RawBlob属性
//-定义为T*ObjArray动态数组存储的任何已发布属性
//（通过Delphi 7-2009上的Rtti.RegisterObjArray）
//-考虑从TOrmNoCase和TOrmNoCaseExtended继承，如果
//您需要常规NOCASE排序规则和更小的排序规则（但不是标准JSON）
//变量字段持久性
