【摘要】 结合云南地震观测数据库建设和云南地震业务系统运行管理模式,在对云南地震观测数据的产生、流程和运用需求充分论述的基础上,按照分布式数据库系统的技术特点和规范,详细设计了分布式地震观测数据库的节点分布构架、数据分布策略、数据分布存储、节点间数据库复制计划,并以省中心节点和红河州节点为例,实现了云南分布式地震观测数据库系统,对分布式数据库系统环境下的应用作了初步探讨,为实现“十五”项目“地震信息服务系统”提出的数据共享目标做出了有益的探索。更多还原

【Abstract】 Combining with Yunnan Earthquake Observation Distributed Database(DDB) building and Yunnan Seismic Professional System Operation and Management Mode,we discussed the produce,flow and application demands of observed earthquake data sufficiently.According to the technical features and criterion of DDB,we designed the node distribution truss,data distribution strategy,distributed storage of data and database copy between nodes of Yunnan Earthquake Observation DDB in detail,and took provincial center node and Honghe Prefecture node as examples to implement Yunnan Earthquake Observation DDB.This is a benefit probe for the realization of the objective of data share suggested by the 10th 5-year Plan Project"Yunnan Earthquake Information Service System".更多还原
