内容管理系统存储层的设计与实现

摘要

为有效达到内容管理系统在海量数据的存储,以及在高并发请求下仍能快速响应用户的请求的目的,在研究了传统存储管理方式和分析了在系统中使用关系数据库将会遇到的问题后,采用开源软件Hadoop作为底层分布式存储基础,设计和实现了此时的内容管理系统的存储层,以满足系统快速读取内容的需求.介绍了系统的内容组织管理模型,针对系统快速读写内容的需求,对读写机制进行了改进、优化和封装,并通过实验测试来验证正确性和可行性.%To provide an effective solution for content management system (CMS) to store mass data, and let the system give fast responses to high concurrent requests, after studying the traditional storage management and investigating some frequent questions of applying relational database system in CMS, a design using the open software Hadoop as the underlying distributed storage infrastructures is proposed. The CMS' s underlying storage layer is also designed and implemented, to meet the needs of fast reading and writing. The model that the system used to organize and manage content is introduced first, then a refined way of reading and writing content is given,then the correctness and feasibility is verified by experiments.
