Torque项目是Apache的公开源代码项目,主要用于生成访问数据库的资源和java代码、提供使用这些代码访问数据库的运行时(runtime)环境。通过使用Torque，你可以使用面向对象方式访问数据库，不再需要编写任何SQL语句。本文中给大家详细的介绍了如何使用Torque框架访问数据库的整个过程，希望能够指导大家熟练使用Torque。

A Peer class has a one-to-one mapping to a Database table. You use each table's associated Peer class to do operations on that table. Peer classes are generated for you automatically.

Peer classes have static methods only, so you would never create objects of Peer classes. It is not necessary to have objects on this level because of the one-to-one mapping with a table. Peer methods are thread safe.

在生成好的PO和Table以后，开发者就可以利用PO来进行对Table的访问了。为了达到这个目的Torque提供了一个运行时环境来保证代码的正确运行。在工程中引入了torque相关的.jar就可以拥有这个运行环境了。  阅读全文

　　主流的Persistence Layer解决方案

　　随着基于J2EE应用的日益增加，出现了很多Persistence Layer的解决方案。目前主要的解决方案有以下几种：

　　◆ 自己编写基于JDBC API的解决方案；

　　◆ 采用ObjectRational Mapping（ORM）工具或者是采用面向对象的数据库（ODBMS）；

　　◆ J2EE/Entity Bean CMP (container-managed persistence)；

　　◆ JDO。  阅读全文
