我有四个表:
ProductAttribute - Stored Product Attribute (Color, Size, etc.)
ProductAttributeValue - Stored Product Attribute Value (Green, 10, etc.)
MapProductAttributeValue - Stored relation between Product Attribute and its Values (COlor-Green, COlor-Blue)
MapProductAndAttributeValue - Stored relation between Product table and MapProductAttributeValue table
如何非规范化这个模式 MySQL?我不想使用 NOSQL。我只想使用 RDBMS 方法还是可以有一些不同的存储机制?
