摘要
文中以需求对策论为指导,分析了Oracle Spatial 10g在解决矿区环境信息库的大规模并行处理、多媒体与面向对象数据类型的存储以及开放性访问接口的技术优势与技术条件;以Oracle公司的Oracle 10g为技术平台,介绍了运用EasyLoader和GeoRasterLoader两个工具构建矢量与栅格空间数据库的方法、过程及最终存储结构。最后,以某矿区水环境数据集作为典型实例,介绍对该数据集中以文本数据形式存储的监测数据以及以点、线、面存储的矢量地理实体和遥感数据的一体化信息库构建实例。研究表明:基于面向网格、基于对象-关系的Oracle 10g为一体化的矿区环境信息库的构建提供了可行、优化的解决方案,并为矿区环境的信息服务和科学研究提供了分布式且开放的数据接口,具有广阔的应用前景。
Taking Demands-Countermeasures Theory as the guide,this paper analyzes the technology adavantages and technology conditions of Oracle 10g Spatial when solving the large-scale parallel processing,the storage of multimedia and object-oriented data types and the opening up of access interface of mine area environmental information database;Then,the methods,process and the final storage structure how to construct spatial database are introduced.Finally,a typical example of mine water environmental data collection is presented in detail.The results shows that: Oracle 10g based on the integration of oriented-grid and object-relations provides feasible and optimized solutions to the construction of environmental information database in mine areas,and distributed and open data interface for information service and scientific research of mine environment,which has broad application prospects.
