一、CMDB
    -采集资产
    -API
    -后台管理
        -资产列表(CURD)
        -业务线列表(CURD)
        -用户列表(CURD)
        -组列表(CURD)
        ...
        ===>简单<===
        公共组件：删改查
        查：
            资产列表(CURD)
                config=[
                {
                    "q":"id",
                },{
                    "q":"name",
                }]
                values_list=["id","name"]
                result=model.TB.objects.filter(条件).values(*values_list)
                #[{},{},{}]                      具体列
                ===>标配：配置+数据操作
