Java中的持久性存储技术——JDBC和JDO

在实际的企业应用程序中,开发人员可以通过多种方式来实现数据的持久化存储。例如,使用Java序列化并存储整个对象的二进制表示;较通用的企业方案是通过EJB来使用应用程序服务器的工具;或者使用JDBC存储在数据库中,还有就是通过JDO。文中主要介绍了JDBC和JDO技术,并把JDBC和JDO作了比较,讨论了各自的特性和不同点,并突出了常见的误解。最后得出一般性的结论:它们是互补的API,每个都为各自的目的而很好地服务。

The Persistence Store Technique in Java JDBC and JDO

In practice of the enterprise application,developer can implement data's persistence store with many ways,for example,using Java serialization and storing the binary presentation about the whole object;more popular enterprise scheme is to use the tools of application server through EJB;storing in the database through JDBC or JDO.Introduces the technique of JDBC and JDO,compares JDBC with JDO,discusses their characteristics and differentia,and shows usual misunderstanding.Final conclude in a general way: they are the complementary API, and every one serves well with their different intents.
