三维地学建模多需海量数据支持,其数据库存储通常采用Oracle的LOB字段,而目前多数Oracle数据库访问接口无法处理大于4 G的LOB字段数据。该文基于面向对象思想,设计并实现了以OCI(Oracle Call Interface)技术为基础的Oracle数据引擎组件,将数据引擎操作的对象划分成多个层次,不仅能处理非海量的常见类型字段的数据,而且支持对4 G以上LOB字段数据的操作。该组件不仅突破了其他技术对Oracle LOB字段访问的限制,而且克服了直接使用OCI接口过于复杂、不利于复用等缺点,具有效率高、资源占用率低等优点。  相似文献

针对现有地理分析模型同多源复杂地学数据之间耦合困难、模型运算数据处理过程复杂等问题,构建了以模型需求模板匹配为基础的多源地理数据自动处理与推送方法。利用元数据对多源地理数据进行统一描述,并从模型的数据需求和任务需求两个角度生成模型需求模板,最后通过基于XML的元数据与模型需求模板的匹配求得数据操作模板。在数据操作模板中应用算子库作为转换工具,实现了数据库数据到模型需求数据的转换,完成模型运算数据的自动推送。基于江苏沿海滩涂数据库的分析案例表明,该文提出的模型模板匹配方法可对模型运行数据进行有效解析,并通过数据操作流的构建实现数据的自动推送。该研究可为服务型GIS的发展及地理模型的集成提供理论参考与方法借鉴。  相似文献
