ORM技术与JDBC？ [英] ORM Technologies vs JDBC?

问题描述

我的问题是关于ORM和JDBC技术，与JDBC和其他方法相比，您决定使用ORM技术的标准是什么？

谢谢。

解决方案

复杂性。

ORM 如果您的应用程序是域驱动的，并且对象之间的关系很复杂，或者您需要使用此对象定义应用程序的功能。 / p>

JDBC / SQL 如果您的应用程序足够简单，只能直接从数据库中提供数据，或者它们之间的关系足够简单。

Martin Fowler的书企业应用程序架构的模式更好地解释了这两种类型之间的区别：

请参阅：网域模型和事务脚本

My question is regarding ORM and JDBC technologies, on what criteria would you decide to go for an ORM technology as compared to JDBC and other way round ?

Thanks.

解决方案

Complexity.

ORM If your application is domain driven and the relationships among objects is complex or you need to have this object defining what the app does.

JDBC/SQL If your application is simple enough as to just present data directly from the database or the relationships between them is simple enough.

The book "Patterns of enterprise application architecture" by Martin Fowler explains much better the differences between these two types:
