-
摘要: 从存储管理和时空语义表现角度给出了时空数据模型的基本设计思想。同时,从时空对象类型及其数据结构、时空操作方面定义了一个面向对象时空数据模型的逻辑结构。Abstract: In this paper, some basic ideas of designing a spatio-temporal data model have been presented from two aspects of storage management and description of spatio-temporal semantics. Meanwhile, spatio-temporal object types and its data structure,spatio tempoal operators about an object-oriented spatio-temporal data model has also been presented.
