煤矿地理空间数据一体化管理的数据模型与数据结构的研究

Research of Data Model and Data Structure of Integrated Management of Coal Mine Geospatial Data

  • 摘要: 在分析煤矿地理空间数据特点与煤矿地理空间实体表达的基础上,文章提出了一种针对不同数据源分别采用E-R数据模型、面向对象数据模型以及对象-关系数据模型的混合一体化管理模型,并给出了该模型的数据表结构。该课题的研究对煤矿地理信息系统的开发具有一定的参考意义。

     

    Abstract: Based on analysis of geospatial data characteristics and entity expression of coal mine,the paper proposed an integrated management model,which adopted E-R model,object oriented data model and object-relation data model respectively according to different data source,and gave data structure of the model.The research on the topic had some reference meaning to development of geographic(information) system of coal mine.
