使对象-关系数据库之间的映射成功的一个秘诀就是理解这两种范例和它们的差异，然后基于这些认识来进行明智的取舍。

One of the secrets of success for mapping objects to relational databases is to understand both paradigms and their differences, and then make intelligent trade-offs based on that knowledge.

必须注意确保对象到关系数据库映射的正确性，理想情况下，应该将代码设计成在需求变更时所需的更改最小。

Proper care must be taken to ensure that object-relational database mappings are correct, and ideally the code should be designed to minimize the changes necessary when requirements change.
