摘要
针对多源、海量、异构分布的4G地学空间数据集成难题,在分析联邦数据库、中间件集成、数据仓库等常用数据集成方法优劣的基础上,提出基于数据仓库与中间件的地学数据集成管理模式;以JB地区2005年度矿区及所属矿山的10种矿产作为数据源,构建基于SQL(Structured Query Language)Server的面向服务的体系结构进行验证。结果表明,该模式既能满足4G地学空间数据异构分布、网络化传输的特点,又能满足数据更新快、实时一致性高的要求,便于在云平台上实现。
According to the integration difficulties of the multi-sources mass isomerism and distribution 4 G geological spatial data, the merits of three commonly used technologies of federated-database middleware and data-warehouse is demenstrated, geoscience data integration and management model based on data warehouse and middleware is proposed; with 10 minerals of baishan mining area in Jilin province in 2005 year as data sources, the SOA（ Service-Oriented Architecture） is designed based on SQL（ Structured Query Language） Server to verify. The results show that the architecture is suitable for heterogeneous distribution and network transmission condition, can satisfy the requirement of data update fast and real-time consistency condition, and is easy to implement on cloud platform.
