助力工业物联网，工业大数据之工业大数据之油站维度设计【十四】

01：油站维度设计

目标：掌握油站维度的需求与设计

路径

• step1：需求
• step2：设计

实施

需求：构建油站维度表，得到油站id、油站名称、油站所属的地理区域、所属公司、油站状态等

设计

数据来源

ciss_base_oilstation：油站信息表

代码语言：javascript复制

select
    id, name, code,
    customer_id, customer_name,
    province, city, region, township,
    status, customer_classify, dt
from one_make_dwd.ciss_base_oilstation
where id != '' and name is not null and name != 'null' and customer_id is not null;

eos_dict_type：字典状态类别表，记录所有需要使用字典标记的表

代码语言：javascript复制

select * from eos_dict_type where dicttypename = '油站状态';

eos_dict_entry：字典状态明细表，记录所有具体的状态或者类别信息

代码语言：javascript复制

select * from eos_dict_entry where dicttypeid = 'BUSS_OILSTATION_STATUS';

ciss_base_baseinfo：客户公司信息表【公司ID、公司名称】

代码语言：javascript复制

select ygcode, companyname from one_make_dwd.ciss_base_baseinfo group by ygcode, companyname;

• 数据有重复，做个去重

ciss_base_customer：客户信息表【客户id、客户省份名称、所属公司ID】

代码语言：javascript复制

select code, province, company from one_make_dwd.ciss_base_customer;

ciss_base_areas：行政地区信息表

• 通过具体的id关联所有地区信息

实现设计

• 所有表按照对应字段关联，获取对应的属性字段

小结

• 掌握油站维度的需求与设计

02：油站维度构建

目标：实现油站维度的构建

实施

建维度表

代码语言：javascript复制

-- 创建油站维度表
create external table if not exists one_make_dws.dim_oilstation(
    id string comment '油站ID'
    , name string comment '油站名称'
    , code string comment '油站编码'
    , customer_id string comment '客户ID'
    , customer_name string comment '客户名称'
    , province_id int comment '省份id'
    , province_name string comment '省份名称'
    , city_id int comment '城市id'
    , city_name string comment '城市名称'
    , county_id int comment '县城ID'
    , county_name string comment '县城名称'
    , area_id int comment '区域id'
    , area_name string comment '区域名称'
    , customer_classify_id string comment '客户分类ID'
    , customer_classify_name string comment '客户分类名称'
    , status int comment '油站状态（1、2）'
    , status_name string comment '油站状态名（正常、停用）'
    , company_id int comment '所属公司ID'
    , company_name string comment '所属公司名称'
    , customer_province_id int comment '客户所属省份ID'
    , customer_province_name string comment '客户所属省份'
) COMMENT '油站维度表'
PARTITIONED BY (dt STRING)
STORED AS TEXTFILE
LOCATION '/data/dw/dws/one_make/dim_oilstation';

抽取数据
