一、与电商业务集成

### --- 电商业务集成环境准备

~~~     开发（建库、建表） => 导入数据 => 执行Hive脚本
~~~     导入Hive的血缘关系

二、电商业务建表

### --- 电商业务建表语句（可省略）：
~~~     创建DataBases;

CREATE DATABASE ODS;
CREATE DATABASE DIM;
CREATE DATABASE DWD;
CREATE DATABASE DWS;
CREATE DATABASE ADS;

三、加载数据

### --- 使用Sqoop加载数据（可省略）：

sqoop import \
--connect jdbc:mysql://hadoop05:3306/ebiz \
--username hive \
--password 12345678 \
--target-dir /data/yanqidw/data/trade.db/orders/dt=2020-07-21/ \
--table yanqi_trade_orders \
--delete-target-dir \
--num-mappers 1 \
--fields-terminated-by ','

sqoop import \
--connect jdbc:mysql://hadoop05:3306/ebiz \
--username hive \
--password 12345678 \
--target-dir /data/yanqidw/data/trade.db/payments/dt=2020-07-21/ \
--table yanqi_payments \
--delete-target-dir \
--num-mappers 1 \
--fields-terminated-by ','

sqoop import \
--connect jdbc:mysql://hadoop05:3306/ebiz \
--username hive \
--password 12345678 \
--target-dir /data/yanqidw/data/trade.db/product_category/dt=2020-07-21/ \
--table yanqi_product_category \
--delete-target-dir \
--num-mappers 1 \
--fields-terminated-by ','

sqoop import \
--connect jdbc:mysql://hadoop05:3306/ebiz \
--username hive \
--password 12345678 \
--target-dir /data/yanqidw/data/trade.db/product_info/dt=2020-07-21/ \
--table yanqi_product_info \
--delete-target-dir \
--num-mappers 1 \
--fields-terminated-by ','

sqoop import \
--connect jdbc:mysql://hadoop05:3306/ebiz \
--username hive \
--password 12345678 \
--target-dir /data/yanqidw/data/trade.db/order_product/dt=2020-07-21/ \
--table yanqi_order_product \
--delete-target-dir \
--num-mappers 1 \
--fields-terminated-by ','

sqoop import \
--connect jdbc:mysql://hadoop05:3306/ebiz \
--username hive \
--password 12345678 \
--target-dir /data/yanqidw/data/trade.db/shop_org/dt=2020-07-21/ \
--table yanqi_shop_admin_org \
--delete-target-dir \
--num-mappers 1 \
--fields-terminated-by ','

sqoop import \
--connect jdbc:mysql://hadoop05:3306/ebiz \
--username hive \
--password 12345678 \
--target-dir /data/yanqidw/data/trade.db/shops/dt=2020-07-21/ \
--table yanqi_shops \
--delete-target-dir \
--num-mappers 1 \
--fields-terminated-by ','

alter table ods.ods_trade_orders add partition(dt='2020-07-21');
alter table ods.ods_trade_payments add partition(dt='2020-07-21');
alter table ods.ods_trade_product_category add partition(dt='2020-07-21');
alter table ods.ods_trade_product_info add partition(dt='2020-07-21');
alter table ods.ods_trade_order_product add partition(dt='2020-07-21');
alter table ods.ods_trade_shop_admin_org add partition(dt='2020-07-21');
alter table ods.ods_trade_shops add partition(dt='2020-07-21');

### --- 加载数据：电商业务脚本(省略了ODS层数据加载)：

~~~     # 加载DIM层数据
sh /data/yanqidw/script/trade/dim_load_product_cat.sh 2020-07-21
sh /data/yanqidw/script/trade/dim_load_shop_org.sh 2020-07-21
sh /data/yanqidw/script/trade/dim_load_payment.sh 2020-07-21
sh /data/yanqidw/script/trade/dim_load_product_info.sh 2020-07-21
~~~     # 加载DWD层数据
sh /data/yanqidw/script/trade/dwd_load_trade_orders.sh 2020-07-21
~~~     # 加载DWS层数据
sh /data/yanqidw/script/trade/dws_load_trade_orders.sh 2020-07-21
~~~     # 加载ADS层数据
sh /data/yanqidw/script/trade/ads_load_trade_order_analysis.sh 2020-07-21

四、自定义分类

### --- 创建Classfication分类

~~~     ——>CLASSFICATION——>name：order_analysis——>Description：订单分析——>Create

### --- 创建Glossary分类

~~~     ——>GLOSSARY——>Name：ODS层——>Short Description：ODS层——>Long Description：ODS层——>Create
~~~     ——>ODS层——>Create Tream——>Name：电商业务——>Short Description：电商业务——>Long Description：电商业务——>Create
