助力工业物联网，工业大数据之客户回访事实指标需求分析【二十三】

1：客户回访事实指标需求分析

• 目标：掌握DWB层客户回访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：基于客户回访数据统计工单满意数量、不满意数量、返修数量等指标

    

  • 数据来源

    • ciss_service_return_visit：回访信息表

      select
          id,--回访id
          code,--回访编号
          workorder_id,--工单id
          create_userid, --回访人员id
          service_attitude,--服务态度
          response_speed,--响应速度
          repair_level,--服务维修水平
          is_repair --是否返修
      from ciss_service_return_visit;
      

      • 1：满意
      • 0：不满意

    • ciss_service_workorder：服务工单信息表

      select
          id,--工单id
          service_userid,--工程师id
          service_station_id,--服务站点id
          oil_station_id --油站id
      from ciss_service_workorder;
