how-to 有如此多的非关系型数据库可选择真是一件好事。积累一些NoSQL相关的知识和初步体验能帮助管理人员、架构师、开发人员将所知道的关系型数据库的 长处和短处跟NoSQL数据库进行对比。关系型数据库和SQL查询语言目前在各种数据库应用程序的设计、开发和管理过程中仍是主要元素和中枢系统。但当我 们需要开始使用云数据库结构时，所有的我们了解的知识和收集的资料都能保证我们能迅速的进行迁移。这完全是根据用户和业务的需求，我们才能做出到底是使用 现有的关系型数据库技术还是使用NoSQL进行替换。
在”SQL 数据库的终结 – 第三篇” 中，我将会告诉大家一些因特网上关于 NoSQL 的资料，过去和将要发生的事件，以及一些相关指导。
你是否正在使用非关系型数据库呢？你是否已经放弃了SQL和关系型数据库呢？你是否正在把你的数据转移到一个公共的或私有的云数据库里呢？请发表评论。
编程就是人生！
