摘　　要：由于Web2.0的快速发展,非关系型、分布式数据存储得到了快速的发展。针对传统关系型数据库逐渐暴露出的性能瓶颈,介绍了非关系型数据库(Non_relational Database,NoSQL)模型及NoSQL数据库,对NoSQL数据库具有的特点做了简单定义,阐述了NoSQL数据库的存储方式,论证了NoSQL比较于传统关系数据库的优点,并介绍了著名的CAP理论。针对NoSQL的大数据量存储机制,总结了主流解决方案的共同特点及共同技术,并对数据库的性能测试结果进行了分析。Due to the rapid development of Web2.0,non-relational,distributed data storage has been rapidly developed. Aiming at the performance bottleneck gradually exposed in the traditional datalSase, NoSQL Model and NoSQL database are introduced,a simple definition of NoSQL database and its features are given,the storage method of NoSQL database is expounded,the advantages of NoSQL as compared with the traditional relational database are demonstrated, and the famous CAP theory is introduced. Aiming at a large- amount data storage mechanism, common characters and common technology of the master solutions are summarized. At last, the per- formance testing results of NoSQL database are analyzed.
