大数据时代传统关系数据库与NoSQL数据库的对比与分析

Comparison and Analysis of Traditional Relational Databases and NoSQL Databases in the Era of Big Data

传统关系数据库能够很好地支持结构化数据的存储和管理,且具有完备的数学理论、完善的事务管理机制和高效的查询处理引擎,因此得到了广泛应用。但随着大数据时代的到来,传统关系数据库无法满足各种类型的非结构化数据的大规模存储和高效处理需求,因此出现了NoSQL(Not only SQL)数据库。本文首先对二者进行了介绍,然后又从多个方面进行了比较和分析。

The traditional relational database can well support the storage and management of structured data, has a complete mathematical theory, a perfect transaction management mechanism and an efficient query processing engine, so it has been widely used. However, with the advent of the era of big data, it is unable to meet the large-scale storage and efficient processing requirements of various types of unstructured data, so NoSQL(Not only SQL) databases came into being. Firstly, the article discussed the both, and then compared and analyzed of the both from many aspects.
