IPV4toIPV6
- 目前可用的IPv4地址已经分配了70％左右，而且B类地址已经基本耗尽。而采用长度为128字节IP地址的IPv6协议，则彻底解决了IPv4地址不足的难题，并且在地址容量、安全性、网络管理、移动性以及服务质量等方面有明显的改进，IPv6也成为下一代互联网络协议采用的核心标准之一-Currently available IPv4 addresses have been allocated about 70 , and the Class B addresses have basically been

iBATIS-SqlMaps-2_cn
- 本文讨论了iBATIS SQL Map最重要的特性。使用SQL Map，能够大大减少访问关系数据库的代码。SQL Map使用简单的XML配置文件将Java Bean映射成SQL语句，对比其他的数据库持续层和ORM框架（如JDO的实现，Hibernate等），SQL Map最大的优点在于它简单易学。要使用SQL Map，只要熟悉Java Bean，XML和SQL，就能使您充分发挥SQL语句的能力。-This article discusses the iBATIS SQL Map of the m
