代码说明：

详细地讨论Sun公司的Java数据对象（JDO）标准。JDO允许我们使用Java对象，支持事务和多用户。与ODBC不同的是，它使我们无需考虑SQL和与数据库有关的其他东西。它与串行化也有所区别，因为它支持多个用户和事务。JDO允许Java开发人员将他们的数据模型用作数据模型，无需在“数据端”、“对象端”之间的转移方面花费大量的时间-detailed discussion of Sun"s Java Data Objects (JDO) standard.

It also Serialization distinction, because it supports multiple users and services.
