基于数据立方体的郑州城市地质数据分类组织

Classification and Organization of Zhengzhou Urban Geological Data Based on Data Cube

地质数据具有多维度属性,采用单一的数据分类方法对数据进行组织,难以满足地质数据多元化应用和服务的需求。针对地质数据难以有效分类这一问题,以郑州市为例,建立了该市多要素城市地质调查数据分类立方体模型,实现了郑州市多要素城市地质调查数据可根据业务需求动态生成数据组织目录,为海量、多源异构地质数据的快速检索与发现奠定坚实的基础。

Geological data has multi-dimensional attributes.It is difficult to meet the demands of diversified applications and services of geologi-cal data by using a single data classification method to organize the data.To solve the difficulty in effective classification of geological data,we established the Zhengzhou multi-factor urban geological survey data classification cube by using the geological data classification cube model according to the data cube theory.Then,we achieved the Zhengzhou multi-factor urban geological survey data todynamicallyorganize data con-tents based on business demands,which laid a solid foundation for the rapid retrieval and discovery of massive,multi-source heterogeneous geo-logical data.
