电子商务数据库设计
自学编程,想设计开发一个购物平台。商品只有一种,但是分为不同的类型,这个数据库该怎么设计呢?比方说书
书:
id: int
name: string
description: text
price: decimal
cover_image: string
书可以按照不同的条件来筛选,比方说按照分类,或者是按照书籍语言,发布时间,价格等等。。是设计一个category表
id: int
name: string
然后分别建立不同的category,然后让一本书归属于这些不同的category呢,还是把这些信息硬编码到书数据表中
id: int
name: string
description: text
language: string
type: string
price: decimal
正确的做法应该是怎样的呢?

如图 ,请注意这只是一个可行的方案,并不是唯一解
(price单位建议用分,用int存储,避免浮点数精度问题)
语言,或者其它杂七杂八的属性你可以放到property属性表,然后具体书是否具有哪个属性在book_property里面加一行记录
分类因为展现比较频繁,所以单独列出,考虑一个关联表book_category的原因是不知道是否允许一本书出现在多个分类里面,如果一本书限死一个分类,那这个book_category可以省略,book表加一列category_id
另外,高阶的搜索和筛选功能你需要搜索引擎,Elastic Search, Sphinx, Xunsearch,Solr等等,你用MySQL一方面性能太差另一方面SQL太复杂,稍微深入之后你可以试着接入
