用非第一范式关系表达GIS时态属性数据

Representing Temporal Attributes in GISs Using Non-1NF Approach

    摘要
  • 摘要: 在对一个土地分化实例所作研究的基础上.提出用非第一范式关系表达属性时态的变化,并对基于这种非第一范式关系的时态属性数据组织与实现技术进行了研究与实验。

     

    Abstract: Managing temporal attributes is one of the main tasks in temporal GISs.Based on an example of land subdivision,the non-1NF approach was used by the authors to represent the temporal attributes in this paper.The corresponding data construct and implementation issues were also examined in the paper.
