【摘要】 结合XML与关系数据库各自在数据管理上的优势,设计了基于XML的遥测数据管理系统。其中,对遥测数据的存储除了直接XML结构化存储外,还提出了“数据分段”的方法存储大数据量参数,在实际系统运行中表现出很高的数据检索效率。由于XML文档在Internet数据发布上具有先天的优势,系统可直接将未解析的XML文档输出到客户端,因此提高了遥测数据的发布能力。更多还原

【Abstract】 By combining the advantages of the extensible markup language(XML) with the data base system,a XML-based data management system is designed and implemented.Based on the structural XML storage,the method to storage a large scale of telemetry data in sections is proposed.The index efficiency of the telemetry data is increased obviously in the operation of the practical system.The distribution ability of telemetry data is increased too.更多还原
