摘要
如何有效组织、管理和维护海量作战数据,实现快速和准确地进行数据访问和控制已成为作战数据管理部门面临的突出问题。基于元数据提出了一种作战大数据资源目录服务技术,构建了集中分区+分布复制的元数据目录的部署结构,确保了数据可靠性和可用性,提高了数据访问效率。分析了元数据目录服务系统层次结构,建立了元数据目录服务模型,并在此基础上设计和实现了基于元数据的作战大数据资源目录服务系统。系统应用表明,该技术可为装备保障数据多样化应用和高可靠服务提供技术解决途径,同时有效支撑了装备保障数据管理系统的构建。
Effective organization,management and maintenance of the massive operation data,and rapid and accurate data access and control have become a prominent problem faced by operational data management departments.Based on the metadata,the operation big data resources catalogue service technology is proposed.The metadata catalogue deployment structure with centralized partition and distributed replication is constructed.The data reliability and availability are ensured.The data access efficiency is improved.The hierarchical structure of metadata catalogue service system is analyzed.The metadata catalogue service model is established.On this basis,the operation big data resources catalogue service technology based on metadata is designed and implemented.The system application shows that the technology can provide technical solutions for the diversified application of equipment support data and the highly reliable services,and effectively support the construction of equipment support data management system.
