摘　　要：针对时间频率科学数据入库与检索效率低、多源异构数据存储管理困难、多用户高并发数据服务能力差的问题,提出了一种基于非关系型(NoSQL)数据库的时间频率科学数据混合存储策略。首先,分析了时间频率科学数据特征及主流NoSQL数据库的特点,结合数据及信息服务需求,提出了基于NoSQL数据库的混合存储策略;然后,基于提出的混合存储策略设计了数据存储系统架构及模型;最后,对提出的存储策略进行可行性和有效性进行验证。结果表明,提出的混合存储策略较传统存储策略性能有较大提升,能够有效地满足时间频率科学数据服务、数据分析及知识获取中对数据实时请求、高并发访问及扩展性的需求。In order to solve problems in storage and retrieval of time and frequency data, such as low retrieval efficiency, management of heterogeneous data, poor service capability of multi-user high concurrent data, a hybrid storage strategy of time and frequency data, based on non-relational(NoSQL) database, was proposed. The reasons of the proposed hybrid storage strategy of time and frequency data are firstly discussed, which are mainly due to the properties of time and frequency data and requirements on services of the data. Then, we design a architecture model of the data storage system. Finally, the feasibility and effectiveness of the proposed hybrid storage strategy are verified. The results show that, compared with traditional storage strategy, performances of the proposed storage strategy are greatly improved, on subjects of real-time data request, high concurrent access, and expandability of time and frequency data.
