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
```
selectid, 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
```
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
```
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】
```
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】
```
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
