| 摘 要： | 数字城市空间信息平台可为国民经济发展、国防建设、人口、资源、环境和灾害等重大社会持续发展问题提供全面的信息共享服务。传统数字城市空间信息平台的封闭性和自身服务器的性能限制了进一步的应用。网格技术能够实现数据访问透明、一体化应用服务、计算吞吐量极大。本文提出了一套基于网格计算的数字城市空间信息平台框架,并对数据网格中的单个计算节点作了基于J2EE三层体系结构的实现。

| Abstract: | Cyber-city's spatial information platform can be served to many social durative development problems such as national economic development,national defense,population,resource,environment and disaster etc with shared information service.But the isolation and server performance of traditional cyber-city's spatial information platform limit its future development.Grid computing can implement data-accessing transparently,seamless application service,and its throughput is huge.A framework of cyber-city's spatial information platform based on grid computing is proposed in this paper,and the individual knot in the data-grid is realized based on J2EE Tri-tier system framework.. |
