* vendors表
*-----------------------------------------------------------------------------
* vendors表存储销售产品的供应商。每个供应商在这个表中有一个记录，供应商ID（vend_id）列用来匹配产品和供应商。
* vend_id 唯一的供应商
* vend_name 供应商名
* vend_address 供应商的地址
* vend_city 供应商的城市
* vend_state 供应商的州
* vend_zip 供应商的邮政编码
* vend_country 供应商的国家
* 这个表使用vend_id作为主键，vend_id为一个自动增量自段
*
* products 表
* -----------------------------------------------------------------------------------------
* products表包含产品目录，每一行一个产品。每个产品有唯一的ID（prod_id）,通过vend_id(供应商的唯一的ID)关联到他的供应商
* prod_id 唯一的产品ID
* vend_id 产品供应商ID
* prod_name 产品名
* prod_price 产品价格
* prod_desc 产品描述
* 这个表用prod_id作为主键，为实施引用完整性，应该在vend_id上定义一个外键，关联到vendors的vend_id。
*
* customers
* ----------------------------------------------
* customers表存储所有顾客的信息。每个顾客有唯一的ID（cust_id）
* cust_id 唯一的顾客ID
* cust_name 顾客名
* cust_address 顾客的地址
* cust_city 顾客的城市
* cust_state 顾客的州
* cust_zip 顾客的邮政编码
* cust_country 顾客的国家
* cust_contact 顾客的联系名
* cust_email 顾客的联系email地址
* 这个表用cust_id作为的他的主键，cust_id是一个自动增量字段。
*
* order表
* ----------------------------------------------------------------------------------------
* order表存储顾客订单。每一个订单唯一的编号（order_num）,订单用cust_id（关联到customer表的顾客唯一ID）与相应的顾客关联
* order_num 唯一订单号
* order_date 订单日期
* cust_id 订单顾客ID（关系到customers表的cust_id）
* 这个表使用order_num作为他的主键，order_num是一个自动增量字段。为实施引用完整性，应该在cust_id定义外键，关联到customers的cust_id
*
* orderitems表
* ----------------------------------------------------------------------------------------------
* orderitems表存储每个订单中的实际物品，每个订单的每个物品占一行。对orders中的每一行，orderitems中有一行或多行。每个订单物品由订单号
* 加订单物品唯一标识。订单物品通过order_num(关联到ordrs中的订单唯一ID)与他们相应的订单相关联。此外，每个订单项包含订单物品的产品ID（他
* 关联物品到products表）。
* order_num 订单号（关联到orders表的order_num）
* order_item 订单物品号
* prod_id 产品ID(关联到products表的prod_id)
* quantity 物品数量
* item_price 物品价格
* 这个表使用order_num和order_item作为主键，为实施引用完整性，应该在order_num上定义外键，prod_id定义外键。
*
* productnotes表
* ------------------------------------------------------------------------------------------------
* 存储与特定产品有关的注释。并非所有的产品都有相关的注释，而有的产品可能有许多相关的注释。
* note_id 唯一注释ID
* prod_id 产品ID
* note_date 增加注释的日期
* note_text 注释文本
* 这个表使用note_id作为主键。note_text使用FULLTEXT搜索进行索引，ENGINE=MyISAM。
