1：安装事实指标需求分析

• 目标：掌握DWB层安装事实指标表的需求分析

• 路径

  • step1：目标需求
  • step2：数据来源

• 实施

  • 目标需求：基于设备安装信息统计安装设备个数、收费安装个数、审核安装个数等指标

    

    • 全新安装数量：install_type = 1
    • 联调安装数量：install_way = 2
    • 产生维修数量：is_repair = 1
    • 额外收费数量：is_pay = 1
    • 安装设备数量：与服务单关联，统计设备的id个数
    • 安装费用：通过工单id从报销单信息中关联得到报销金额
    • 审核完成工单个数：

  • 数据来源

    • ciss_service_install：安装单信息表

      select
          id,--安装单id
          code,--安装单号
          install_way, --安装方式 
          service_id --服务单id
      from ciss_service_install;
      

      • ciss_service_workorder：工单详情事实表

    select
        service_userid,--工程师id

    from ciss_service_order;
    

    

    • ciss_service_order_device：服务单设备信息表

    select

        service_order_id  --服务单id
    from ciss_service_order_device;
    

    • ciss_s_install_exp_rep_02_dtl：报销单明细表

    select
        id,          --报销ID
        workorder_id,--工单id
        money5       --报销金额
    from ciss_s_install_exp_rep_02_dtl;
    

    • ciss_service_install_validate：设备安装审核信息表

    select
        id,          --审核ID
        workorder_id,--工单id
        has_validate --审核状态，1-已审核，0-未审核
