数据库中表结构的设计原则

纸上得来终觉浅,
觉知此事要躬行.

As for the table creation in ORACLE, especially in designing a practical application, 3NF is enough. But if you plan a large scale database application, you'd better sometimes consider 4NF. You'd better put your concentration on the efficency, that's important.

我倒觉大数据库得有时是需要牺牲存储来换速度呢
不能说范式级别一定要高才好呢

取舍在于具体的应用

原则是人设计的，所以人可以破坏原则，为了更好的应用。原则是个范畴，冗余可以改善其特定应用中不合理的地方。

主要是如何平衡速度与存储效率地问题

我觉得主要是扩展性好，符合第三范式就可以啦
