基于空间数据仓库的水文信息共享及其安全性浅析

Analysis for the hydrological information sharing based on the spatial data base and security

为解决水文信息共享问题,本文从分析水文数据本身固有的特性出发,建立了基于空间数据仓库的具有多层维度和度量属性的水文信息共享数据模型,结合面向对象的思想,提出水文信息单元,并探讨了以之建立水文信息数据仓库的方案及其信息共享后的安全性问题。

To solve the problems of hydrological information sharing, this paper analyses the inherent characteristics of hydrological data, sets up a spatial data base with a multi-dimension and measure attributes of hydrological data model to share information, combined with object-oriented idea, the hydrological information unit, and examined in order to set up hydrological information of the program and its data base security information-sharing issues.
