基于数据仓库的国土资源引擎数据库系统

国土资源信息是一个非常大的资源仓库，它所涉及的信息资源大国家宏观发展规划，小至居民日常生活细节，充分开发利用国土资源信息在我国具有很大的潜能，也是保证国民经济信息迫切需要解决的问题，国土资源引擎数据库存储了国际资源搜索引擎系统中大量的查询数据信息和类目分检查信息，是国土资源搜索引擎数据库系统的核心和支撑，鉴于引擎系统对相关数据的广度计算和深度计算都有较高要求，为此采用了数据仓库和动态数据库系统的数据管理技术，详细阐述于数据仓库的国土资源搜索引擎系统的开发过程和工作流。

The search-engine database of land and mineral resources based on data warehouse

Land and mineral resources information constitutes a very large datawarehouse. It relates to various information re-sources ranging from state development planning to resident daily-living. Therefore,there is a great potential to fully utilize and develop land and mineral resources information in our country,and it is urgent problem to be solved for promoting national eco-nomy development. Search-engine database of land and mineral resources information storages a large amount of information about data query and category,and it lays foundation of Search-Engine System of Land and Mineral Resources Information(SESLMRI). Because the search-engine requires a large amount of calculation of wide scope and in depth,the technique for data warehouse and dynamic database is utilized. In this paper,the development and work flow of SESLMRI are elucidated in detail.
