求一B2C商城SKU的数据库设计及编程思路
现在电子商务网站很火，里面卖的东西也很多，就会有SKU的管理
现在求一思路，能实现像京东商城那样的功能
http://www.360buy.com/product/1000218275.html
要求多规格的产品要实现每一个规格都是一个独立的商品，并且独立产品ID
比如某一衣服有红色，黑色，M,L
那就有：红M，红L，黑M，黑L
这样的话方便库存的管理
现在问题是怎么实现好
并且方便SKU的修改，增加，删除及以后的扩展？
是把所有SKU生成的产品放在一个表里面，还是建立一个主表存放商品信息，然后SKU建立独立表
前台展示怎么实现
如果某一商品SKU数量过多，肯定不能全部展示
还有在产品规格选择的页面，怎么实现像京东那样的功能
每一个组合好的规格都是独立的产品ID，不要用JS
谢谢！

淘宝的每一个SKU都有一个数值表示.我想肯定会有一个独立的SKU表
前台当然是按照类来展示了，然后根据用户自己的需求再提交不同的SKU深入的获取更多的数据吧。
别的不清楚，看看有没设计过这类东西的人来提点意见.

你只要认真学习一下“图书馆管理学”就都清楚了
由此可知，为什么正规的计算机软件教程中都有一个“图书管理”项目
