动态目标时空数据高效管理与分析研究

摘要

Dynamic target has a lot of characteristics such as spatiality, timeliness, multidimensionality, magnanimity,complexity and uncertainty, but the traditional DBMS can't provide an effective way for its position modeling, semantic expression and index.In order to solve this problem, this paper presented a general framework to model, analyzed and managed the dynamic target spatio-temporal data by analyzing the dynamic target.This framework uses three-layer structure,insuring the system with high flexibility and expansibility.Finally, a prototype system based on the framework was given, and the main componented of platform were analyzed and expounded.%动态目标具有空间性、时间性、多维性、海量性、复杂性和不确定性的特点,而传统的DBMS已不能有效地对其进行位置建模、语义表达、索引.首先,分析了动态目标数据建模、动态目标多时态性、动态目标多维性、动态目标分布性等4个方面存在的问题.然后,提出了一个对动态目标时空数据进行建模、管理与分析的总体框架,并对框架各关键技术进行了深入的研究.该框架采用三层体系结构,使得系统有较高的灵活性和扩展性.最后,基于该框架,给出了一个原型系统,并对其主要构成平台进行了分析与阐述.
