【摘要】 本文从煤炭地质信息服务需求、系统构架、数据管理模型、系统平台、应用技术等方面阐述了煤炭地质信息服务系统建设思路,提出了以项目为管理单位、以文件为服务单元、以Oracle数据库为目录索引,调用一个基于分布式文件存储的Mongo电子文件库的数据库联合管理体系,采用独立采集工具,结合内外网完全物理隔离的方式保障数据安全。其中内网基于intranet运行内部信息综合管理系统,实现数据的集成、管理与查阅,外网基于Internet提供煤炭地质信息广域服务。该系统的建成将提升煤炭地质信息服务的深度和广度,发挥行业地质信息服务在社会经济发展中的重要作用。更多还原

【Abstract】 This paper states the idea for building coal geology information services respectively from such aspects as the general needs and system framework,data management model,system platform,applied technology etc.One combination management system is proposed which management unit based on project,service unit based on file,to accesses distributed electrical file sets physically restored as MongoDB format,through catalogue indexed as Oracle database.The system safety is guaranteed by the standalone acquisition tools and separated networks between inner and outer.Inner comprehensive management system runs on intranet,fulfills data integration,management,search functions etc.External system is based on internet to offer coal geology information services.Building the system will extend the breadth and depth of coal geology information services,and promote important effort to social economic development from information services of industry geology.更多还原
