为什么面向对象的数据库还没有成功？ [英] Why have object oriented databases not been successful (yet)?

问题描述

这就是问题。只有一个原因，你认为为什么OODB失败或为什么许多系统现在仍然使用关系数据库。

That's the question. Give only one reason you think why have OODB failed or why many systems nowadays still use relational databases.

推荐答案

一旦？另一个原因是关系数据库在数学中有着坚实的基础：从关系的定义，直到正常形式，理论是坚实的。的确，关系模型不能很好地映射到OO，但是IMHO的模型的优点和稳定性超过映射问题。

Can we answer more than once? Another reason is that relational DB's have a strong foundation in mathematics: from the definition of a relation, right through to the normal forms, the theory is rock solid. It is true that the relational model does not map well to OO, but IMHO the benefits and stability of that model outweigh the mapping problem.
