SQL数据库的终结(第二篇)?

在 “SQL数据库的终结? (第一篇/共三篇)” 里我简要介绍了一下关于SQL语言和关系型数据库的背景知识,包括它的过去和将来,介绍了一些以隐藏数据库编程的复杂度为目的模式框架的流行和NoSQL数据库的兴起。在本文的第二篇里,我将介绍一些现有的开源的或非开源的NoSQL数据库。之后,在第三篇里,我将引导你去发现网上的关于NoSQL的资料,告诉你一些跟NoSQL相关的已经发生的和即将发生的一些事件,给软件开发者提供一些这方面的指导。

你想象不到,如今竟然有了那么多开源的/非开源的NoSQL数据库产品。而同时,每天都有新的品种出现。如果我的列举中遗漏了你喜爱的NoSQL数据库,请发评论告诉我。下面你将看到的就是各种不同类型的NoSQL数据库产品:面向文档的,面向集合的,面向列的,面向对象的,面向图的,面向有序集合的,面向行的,等等。

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!
