推荐答案

EAV有几个缺点：

• 数据库层不能强迫属性名称是正确的，所以你必须做，在code


• 搜索性能很慢，如果你的价值观在EAV表过滤


• 性能也慢，如果你尝试基于EAV表
的值加入其他表

• The database layer can't force attribute names to be correct, so you have to do it in code
• Search performance is slow if you're filtering on values in the EAV table
• Performance is also slow if you try to join other tables based on the values in the EAV table

但是如果你需要一个灵活，动态的属性集您不需要寻找或属性值加盟，EAV是一个很好的解决方案。

But if you need a flexible and dynamic set of attributes and you don't need to search or join by the attribute values, EAV is a good solution.
