摘　　要：随着大数据和信息化技术的快速发展,大量多源异构数据支持核应急决策成为可能,合理的核应急数据库设计直接影响核应急决策系统数据访问的效率。本文设计了一种关系型与非关系型耦合数据库(G-R-M),在开源分布式关系数据库Greenplum的基础上整合非关系型数据库Redis、MongoDB,对核应急信息进行优化管理,解决了数据事务性和高效存取的矛盾。以核事故状态下应急防护措施选用分析为案例,应用本文设计的G-R-M数据库开展了传统关系型数据库与改进后数据库在数据查询性能方面的对比测试。结果表明,G-R-M数据库较大程度提升了核事故早期信息的查询调用效率,可为核事故应急决策提供快速数据支持。With the development of big data and information technology,a large number of multi-source heterogeneous data can be used to support nuclear emergency decision-making.Reasonable design of nuclear emergency database directly affects the efficiency of data access of nuclear emergency decision-making system.In this paper,a type of relational and non-relational coupled database(G-R-M)is designed,and the non-relational databases Redis and MongoDB were integrated on the basis of Greenplum,an open-source distributed relational database,to optimize the management of nuclear emergency information and solve the contradiction between transactional data and efficient access.Taking the analysis of emergency protection measures under the state of nuclear accident as an example,the G-R-M database designed in this paper is applied to carry out the comparative test of the traditional relational database and the improved database in data query performance.The results show that the G-R-M database greatly improves the query and invocation efficiency of early nuclear accident information,and can provide fast data support for nuclear accident emergency decision-making.
