一、数据库设计如图：
mysql> show tables;
+-------------------------------------+
| Tables_in_macy |
+-------------------------------------+
| rank1_cate_urls |
| rank2_cate_urls |
| rank3_cate_urls |
| rank4_prod_specific_info |
| rank4_prod_specific_review_products |
| rank4_prod_specific_review_reviews |
+-------------------------------------+
二、一共设计了6个tables.然后，分别存放
1） 第一级url,
mysql> describe rank1_cate_urls;
+-------------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------------+--------------+------+-----+---------+-------+
| cate_name | varchar(100) | NO | | NULL | |
| cate_url | varchar(500) | NO | PRI | NULL | |
| request_situation | varchar(10) | YES | | NULL | |
+-------------------+--------------+------+-----+---------+-------+
2） 第二级url,
mysql> describe rank2_cate_urls;
+-------------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------------+--------------+------+-----+---------+-------+
| upper_cate_url | varchar(500) | NO | MUL | NULL | |
| upper_cate_name | varchar(100) | YES | | NULL | |
| cate_name | varchar(100) | NO | | NULL | |
| cate_url | varchar(500) | NO | PRI | NULL | |
| request_situation | varchar(10) | YES | | NULL | |
+-------------------+--------------+------+-----+---------+-------+
5 rows in set (0.00 sec)
3） 第三级url.
mysql> describe rank3_cate_urls;
+-------------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------------+--------------+------+-----+---------+-------+
| upper_cate_url | varchar(500) | NO | MUL | NULL | |
| upper_cls_name | varchar(100) | YES | | NULL | |
| cate_name | varchar(100) | NO | | NULL | |
| cate_url | varchar(500) | NO | PRI | NULL | |
| request_situation | varchar(10) | YES | | NULL | |
| now_price | float | YES | | NULL | |
| old_price | float | YES | | NULL | |
| web_id | varchar(10) | YES | | NULL | |
+-------------------+--------------+------+-----+---------+-------+
8 rows in set (0.00 sec)
4） 具体产品信息。
mysql> describe rank4_prod_specific_info
-> ;
+-----------------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |

| img_request_situation | varchar(10) | YES | | NULL | |
+-----------------------+--------------+------+-----+---------+-------+
10 rows in set (0.01 sec)
5） 根据review package提取的product信息，
mysql> describe rank4_prod_specific_review_products;

+------------------------------+--------------+------+-----+---------+-------+
18 rows in set (0.01 sec)
6） 根据review package提取的review信息。
mysql> describe rank4_prod_specific_review_reviews;
