ORM提供了实现持久化层的另一种模式，它采用映射元数据来描述对象关系的映射，使得ORM中间件能在任何一个应用的业务逻辑层和数据库层之间充当桥梁。
如以下示例:
public int GetSystemAccreditMessageInfo(AccreditParam param)
{
var where = new Where<User>();
var countMesage = ;//记录提醒次数
HttpCookie cookie = HttpContext.Current.Request.Cookies["UserLogin"] as HttpCookie;
if (cookie["Login_id"] != null)
{
where.And(d => d.id == cookie["Login_id"].ToString());
}
where.And(d => d.Del_state == );
var fs = DB.Context.From<User>()
.Select(User._.All, Power._.All)
.InnerJoin<Power>((a, b) => a.Role_id == b.id)
.Where(where);
if (fs.First().Authority == "")
{
countMesage = ;
}
else if (fs.First().Authority == "")
{
countMesage = DB.Context.From<Accredit>().Where(d => d.OAuditor_signature == null || d.OAuditor_signature == "").Count();
}
else if (fs.First().Authority == "")
{
countMesage = DB.Context.From<Accredit>().Where(d => d.TAuditor_signature == null || d.TAuditor_signature == "").Count();
}
else if (fs.First().Authority == "")
{
countMesage = DB.Context.From<Accredit>().Where(d => d.OAuditor_signature == null || d.OAuditor_signature == "" || d.TAuditor_signature == null || d.TAuditor_signature == "").Count();
}
return countMesage;
}
